Perfection
down to the smallest detail
CONTENTS
For many years, Cherry snap
switches and keyboards have been
synonymous with quality and reli-
ability. Cherry is a trademark of ZF
Electronics GmbH, a leading supplier
of electronic components. Whether
in household appliances, industrial
applications, vehicles or input sys-
tems, electronic components ensure
reliable operation as well as safety
and comfort. Our Quality Assurance
System is ISO 9001 and TS 16949-
certifi ed and our Environmental
Management is ISO 14001-certifi ed.
In our experience you need a little advice to get the best out of your switches.
This is why we always start by asking users for detailed information on the
intended scope of application, its basic conditions and all associated speci-
fi cations and data. We regard this as an absolutely indispensable fi rst step.
This catalogue is intended only as a reference document. No responsibility
is taken for the correctness of the details. We reserve the right to make
changes which are minor or serve the purpose of progress.
The technical details relate only to the product specifi cations; product
characteristics are not warranted. We reserve the right to make technical
changes and adjustments due to changed delivery opportunities up to the
contract signing. Only our general sales and delivery conditions apply. We
will gladly send you these on request.

PHILOSOPHY
What makes the difference between
a good and an excellent technical so-
lution? Reliability, the power of inno-
vation, these are the foundations of
success. But how can success be
achieved? Is there a formula which
can be transferred to all industries?
We think there is.
The quality of a total solution is determined by the quality of its compo-
nents. A fault in a component which only costs a few cents can paralyse
everything. Perfection down to the smallest detail is therefore the basis
of our philosophy as a supplier of mechatronic components. Another is
attuning the individual elements optimally to one another. Therefore, we
see ourselves as our customers‘ active partner when it comes to developing
new products.
Our record proves we are right. For many years, Cherry snap switches and
keyboards have been synonymous with the highest quality and reliability.
This principle has also made us one of the leading suppliers of electronic
components. Regardless of whether you use our products in household
appliances, industrial applications, in the automobile industry or for input
systems – you can rely on safety and comfort in addition to reliable perfor-
mance.
It’s not the size which determines
the power, but rather each individual
component.

LOCATION AND QUALITY
Customer satisfaction grows with quality.
And quality with closeness to the customer.
With ever-shorter product cycles, the development time for new products is
also being reduced. In order to guarantee maximum quality, close cooperation
among all partners is important. We interpret the term “close cooperation” in
an old-fashioned way – and wherever possible, we prefer personal contact with
our partners.
6
To be as close to our customers as possible was the principle of Cherry Electrical Products Corporation, which was founded in the USA in 1953.
In 1964 we established a subsidiary in Germany and in 1972 in England.
Additional European subsidiaries followed in France and Czech Republic in 1985 and 1992, respectively. Today, the company acts on a global basis – with
sites throughout the world: in North America and Europe as well as in Asia and Australia. Proximity on location allows us to react quickly to regional or
individual requirements. We continue this philosophy while integrating the Cherry trademark in ZF Electronics GmbH. Being part of a worldwide network,
we can thus be even more responsive to customer and market requirements.

GROWTH, INNOVATION AND ENVIRONMENT
Customer satisfaction grows by quality.
And quality by closeness to the customer
Growth and success across more
than 50 years are no accident, but
the result of a sustainable company
strategy. A strategy which is applied
equally to customers, employees,
our own products and the environ-
ment. This guarantees that our inno-
vations will fall on fertile ground in the
long and short term – and it will en-
sure growth for us and our partners.
Quality and environment
For us, environmental consciousness is more than the fulfi llment of a duty;
we live it every day. Therefore, years ago we introduced an integrated man-
agement system based on the ISO 9001, ISO 14001 and TS 16949 stand-
ards, whose quality and environmental standards have become second
nature for our employees. In order to comply we must fulfi ll and even exceed
the requirements of our customers, suppliers, investors, employees and, last
but not least, the public, through consistent process orientation. This is also
one of the reasons why our company has been honored with several awards
in recent years.
Quality guideline
Customer satisfaction
In the context of a cooperation based on partnership and trust it is our
major objective to fully live up to our customers' expectations.
Competitiveness
We can ensure ZF’s long-term corporate success by providing innovative,
high quality, and cost-effi cient solutions for a global market
Sense of responsibility
The prerequisites for achieving optimum working results are a distinct
awareness of quality as well as assuming responsibility both for oneself
and for the Group.

Principles of environmental protection
Cherry products are contributing to the technical progress on a global
basis. However, this also means that the company has a responsibility to
continuously improve the environmental compatibility of its products over
their entire life cycle and to reduce the strains placed on natural resources.
The Environmental Policy is checked regularly and is binding for all em-
ployees. It is based on the following principles:
1. We design our products and production processes in as energy and
resource-effi cient a manner as possible. We use state-of-the-art environ-
mentally friendly technologies whenever investments are made.
2. We put appropriate measures into place to ensure that environmen-
tally damaging incidents are avoided wherever possible and properly
contained in the event of any incident. We comply fully with all relevant
environmental directives.
3. We involve our employees in the development and implementation of
our environmental policy. We regularly train and motivate them so that
they can actively assist in shaping our environmental protection policy.
4. We are continuously improving operational environmental protection.
Our suppliers are taken into account during this process.
5. We implement the objectives we set ourselves right around the world
with the assistance of appropriate management systems, we check the
agreed performance levels on a regular basis and, if any discrepancy is
detected, respond rapidly with appropriate remedial action.
6. In matters relating to environmental protection, we engage in dialogue
with customers, suppliers, authorities, and all local interested parties.
Furthermore, we regularly report on the consequences of our activities
Employee satisfaction
ZF’s effi ciency is determined by our highly motivated staff. By involving all
stakeholders and continuous communication, our employees' satisfaction
can be maintained on a permanent basis.
Process-oriented management approach
Applying effi cient processes with balanced interaction to achieve highest
product and service quality – that is the basis for our management system.
Partner supplier
Our suppliers make an essential contribution to the quality of our products.
In order to achieve common quality objectives we cooperate with our sup-
pliers as partners.
Permanent improvement
The principle of continuous improvement is an important element of our
actions and secures corporate success for the future.

PRODUCTS
Diversity generates options.
Options result in exactly solutions for
your requirements.
Higher, faster, further – the demands for technical developments are increasing,
while their size is being reduced. A challenge also for the engineers of the indi-
vidual components. To fulfi ll both the requirements and the unusual demands of
our partners, we have created a broad spectrum of switches. Decades of ex-
perience in the development and manufacture of switches equates to the best
solution for your application. The following pages present a detailed overview of
our ranges, which are divided into three types of switches. But in addition to the
switches presented here, we offer several other broad product lines, including
electronic controls, mechatronic assemblies, sensors and rocker switches.

Actuator
Applying force to the actuator of a snap switch releases the snap-action
mechanism, which in turn triggers the switching operation.
Auxiliary actuator
It is possible to attach an auxiliary actuator to a snap switch in order to
meet the specifi c requirements of a given application. Doing so usually
alters the travel and forces involved in the switching operation, depending
on the length of the levers. By attaching an appropriate auxiliary actuator,
it is possible to increase travel and/or reduce the actuating force required.
Terminals
COM (Common = 1): Base terminal
NC (Normally Closed = 2): The contact is closed in the rest position, that
is, the terminal is connected to COM. When
the switch is actuated, the contact opens.
NO (Normally Open = 4): The contact is open in the rest position, that
is, the terminal is separated from COM. When
the switch is actuated, the contact closes.
Contact gap
(contact opening distance)
The contact gap is the distance between a pair of open contacts. For snap
switches, it is usually around 0.3 mm. Generally speaking, for switches
with contact gaps < 3 mm, additional measures are
necessary for separation from the mains. These switches bear the mark µ
for European approvals. Switches with a contact gap > 3 mm can general-
ly be used directly for separation from the mains. Please check the device
specifi cations applying to your particular product, and if there is any doubt,
please clarify with the responsible testing agencies.
Clearance
and creepage distance
Clearance is the shortest distance through the air between two electrically
conductive parts or between an electrically conductive part and a metal foil
affi xed to an accessible surface of some insulating material. The creepage
distance is the shortest distance along the surface of an isolating material
between two electrically conductive parts or between an electrically con-
ductive part and a metal foil fi xed to an accessible surface of the insulating
material.
LEXICON
Snap Switches –
Defi nitions and descriptions
Snap switches are activated by a
spring-operated (or “snap-action“)
mechanism. Depressing the actuator
triggers the switching operation, with
a pre-defi ned force and travel. The
switching speed itself is largely inde-
pendent of the speed of actuation.

Actuator positions
Dimensions for actuator positions are always specifi ed in relation to a given
reference line.
Rest position
The rest position is the position of the actuator when no external force is
being applied. Sometimes referred to as the “free position”.

mechanism is actuated.
Final position (total travelled position)
The position of the actuator at the end of its travel.
Reset point (mech.)

at which the spring-operated mechanism snaps back to its original posi-
tion.
Actuator travel
Pretravel
The distance travelled between the actuator’s rest position and the switching
point.
Overtravel

Conversion US-Units
Inch / millimeter
Generally, measures in this catalogue are based on the metric system and
indicated in millimeter (mm). For the conversion please use the following
relation:
1 millimeter = 0.03937 inches
Example: 27.8 mm x 0.03937 = 1.094 inches
And for the reverse calculation:
1 inch = 25. 4 millimeters
Example: 0. 51 inches x 25.4 = 12.95 mm
Forces
The specifi cations of the operating force for the switches are indicated
in hundredth Newton (cN). For the conversion please use the following
relation:
1 Newton (N) = 100 cN = 101.972 gf
1 cN = 1.01972 gf
Example: 250 cN x 1.01972 = 254.93 gf
The re-conversion corresponds to:
1 gf = 0.981 cN,
Example: 850 gf x 0.981 = 833.85 cN

LEXICON
Operating life
The operating life specifi es the minimum number of switch cycles within
the specifi c values. It depends on a large number of parameters that
are determined by the intended application case. Among these are, for
example:
switched current and switching voltage
type of load (e.g. ohmic, inductive or lamp load)
Combination of materials in actuating element/actuator
Actuator type
Actuator speed
Switching frequency (switching cycles / min)
Pretravel / Overtravel
Environmental factors such as climate conditions or harmful gases
(e.g. SO2)
Please note:
Media such as greases, oils and materials which contain silicon must not
be used on the switch. There is a distinction between mechanical and
electrical operating life.
Mechanical life
Indicates how often a switch can be actuated without an electrical load.
Mechanical endurance is calculated by actuating the snap switches axially
in relation to the actuator in a sinusoidal pattern using about 80 % over-
travel at a switching frequency of 4 Hz at room temperature.
Operating life, temperature resistance,
vibration and electric resistance
16
Electrical life
The selection of the optimal contact material has great infl uence on the
operating life. The electrical life test is conducted at rated voltage, rated
current and resistive load at 23 °C ambient temperature. The lower the
electrical current, the longer the electrical life – under some circumstances
it may even equal the switch’s mechanical life.
Please note:
For switching loads which deviate from the values specifi ed in the cata-
logue, we recommend that you discuss the issues involved with Cherry.
This is especially important if you are using other loads as linear resis-
tances. These can be electrical circuits with inductive resistances (mo-
tors), capacitive resistances (condensers) or lamp loads. To ensure that
a switch reaches the maximum of its electrical operating life, the switch
should not be subjected to pressure in its rest position (pre-stressed)
and at least 50 % of the available overtravel must be used. Operating life
specifi cations for direct current loads are available on request. Where
higher switching capacities are involved, we recommend the use of fuses
to provide protection against arcing.
Please note:
Since the operating life of a snap switch depends on a number of factors,
we recommend that fi eld trials be performed in order to establish the likely
electrical life of a switch in a given application. This is especially recom-
mended when the application deviates considerably from the test condi-
tions described above. Our specialists are always ready to provide you with
more advice regarding possible solutions for your particular application.
Behaviour at
different temperatures
Depending on the model, the operating temperatures of our switches range
from -25 to +70 °C and -40 to +150 °C. If you attempt to use a switch at
operating temperatures either above or below those recommended for your
particular model, the switch‘s material properties will change and
its reliability will be affected. Where switch model codes start with “T”
(e.g. 40T125 in compliance with EN 61058), the switches involved have
been approved for use at the corresponding temperatures.
Vibration and
shock resistance
Snap switches are naturally fairly resistant to shocks and vibrations thanks
to their minimal mass of moving parts. They are at their most resistant
when the actuator is in the rest position or end position, when vibration
resistance is as high as 5 g at 20 – 200 Hz while shock resistance attains
50 g (6 ms).
Please note:
Snap switches are more susceptible to vibrations at the switching point
and at the release point. In certain conditions, this could result in transient
make or break contacts (bouncing) to the detriment of
the switch‘s operating life. This is why snap switches which are regularly
exposed to vibration should, wherever possible, not be actuated slowly.
Electric strength
The electric strength of our snap switches – in the case of models suited
for mains voltages – exceeds 1500 V AC between conducting parts and the
earth and 750 V AC between the terminals (open contacts) measured over
a period of one minute at an ambient temperature of 23 °C ± 5 °C, relative
humidity of < 70 % and normal atmospheric pressure.
17
LEXICON
Operating speed
Snap switches are suitable for a broad spectrum of operating speeds. How-
ever, extremely slow or fast actuations can affect the switch performance
and operating life. For product-specifi c values, please see the technical
specifi cations. The maximum switching frequency (switchings/s) is limited
by the electric load. With low switch loads, up to 10 actuations per second
are possible.
Please note:
Sudden actuation must be avoided since it decreases the mechanical
operating life.
Contact bounce
Bounce time is the time between the moment closing contacts fi rst touch
and fi nal (defi nitive) contact closure. The typical bounce time for our snap
switches is between 1.5 and 3 ms, depending on the series.
Transit time
In two-way (double-throw) switches, transit time is the time between
the moment the break contact element (NC contact) fi rst opens and the
make contact element (NO contact) fi rst closes. Transit time is generally
determined by design features such as e. g. contact travel and elastic
characteristics.
It generally varies between 3 and 10 ms, depending on the model.
Please note:
If transit time is critically important to the functioning of your applica-
tion, don‘t hesitate to contact us.
Contacts
We supply switches with standard and crosspoint contact technology. For
low-voltage and low-current applications, we strongly recommend the use
of gold crosspoint contacts. The reduced surface area of the cross-shaped
contacts means that the surface pressure is greater, which in turn enhances
reliability. Standard contacts are more suitable for higher switched loads.
Contact materials
Gold and gold alloys: primarily AuAg; AuAgPt
Silver and silver alloys: primarily AgNi; AgSn02
Gold alloys are especially suitable for low currents and voltages. Typically
they are used in the range from 5 V, 1 mA DC to 12 V 100 mA DC. But it
may also make sense to use them in switches which are only occasionally
operated or in atmospheres with a high sulphur content.
For switching heavier loads, it usually makes sense to use silver or silver
alloys. In this case, the range typically extends from 12 V, 100 mA DC to
250 V 21 mA AC.
Please note:
Because choosing the right contact materials depends on a large number
of factors, such as switching voltage and current, operating environment,
atmospheric conditions, etc., we are always pleased to advise you on the
best choice of material for your application. Before making any fi rm deci-
sions, we do advise you to carry out fi eld trials of our switches in real-life
conditions.
Operation, contact types
and materials
18
Materials
For our standard switches, we use high-quality, cadmium-free plastics
which are optimized for the intended application. As a rule, we seek to
avoid the use of toxic or hazardous materials. You can fi nd out more about
our materials policy by consulting our hazardous substances exclusion list.
Behaviour of materials in fi re
Insulating materials which are directly connected to electrically conduc-
tive parts are classifi ed according to their degree of fl ammability. Most of
the materials we use to manufacture housings are self-extinguishing and
categorised under the UL 94 V0 standard.
Tracking resistance
Most of the insulating materials we use in our snap switches have a proof
tracking index of PTI 250 (PTI 300, e.g. D4) or PTI 175 (PTI 250, e.g.
DB, DC). This means that they are capable of 50 drops of test fl uid at a
test voltage of 250 V without producing any leakage current (IEC 60112).
RoHS
Switches without leads already conform to RoHS. Switches with leads
are available in RoHS-conforming models on request. In case of further
processing with lead-free soldering, the product-specifi c solder recommen-
dations must be heeded.
Glow wire test
The insulation materials used for snap switches with ENEC approval fulfi l
the required fi lament tests GWFI according to the household appliance
standard IEC 60335-1 at 850 °C and GWIT at 775 °C or alternatively the
fi lament test GWT at 750 °C.
Contact resistance
The contact resistance of snap switches is composed of the contact resis-
tance and the resistance of the conductive parts. It depends primarily on
the construction and the contact material. The contact resistance of silver
contacts is max. 100 m , of gold contacts max. 50 m when they are new.
Insulation resistance
The insulation resistance between the conductive parts of our snap switches
and a conductive underlay or between the open contacts exceeds 10 M
when they are new, measured over a period of one minute at room tem-
perature with 500 V DC.
Caution: humidity and soiling can decrease the insulation resistance.

Please note:
Cherry snap switches should only be installed by trained staff. Gener-
ally, adherence to the required air gap and creepage distance must be
ensured with suitable measures. These must also be adhered to for lines
connected to the switch.
If installation is to occur on a conductive surface, insulating panels must
be used. Under some circumstances, their use is also required between
switches installed alongside one another and plug-in connections. Switches
can be installed in any position. Power transmission to the connections of
the switch is not permitted. When fastening with screws, screws with a
co-planar contact surface must be used (e.g. in accordance with DIN 84,
DIN 912). Smooth, solid surfaces are suitable for installation.
Exceeding of the following tightening torque values is not permissible. We
recommend trial installations. If you wish to install your switches using
coupling pins, we would be happy to advise you on suitable parameters.
Please note:
If components are likely to be subjected to vibrations, we advise you to
take additional measures to secure them. With solder connections, the
product-specifi c solder recommendations must be heeded in order to
prevent damage or destruction of the switches.
Please note:
Cleaning agents and solvents in proximity to the switches can impair
their function, especially in case of watertight models. When using
greases (especially mineral oil-based ones), we recommend consultation
with ZF Electronics. The switching action may be initiated by a force act-
ing vertically on the actuator, or by an angled actuation lever.
Example:
The angle of the lever in relation to the top of the switch housing should
not exceed 30 °. The precise angle will also depend on the actuating speed,
combination of materials, surface characteristics and so on. In case of aux-
iliary actuators with rollers or simulated rollers, steps should be taken to
ensure that the lever does not impede its own action. This means that the
direction of actuation should be away from the actuator’s mounting point
towards the roller, and the angle of actuation should be adjusted to allow
for the geometry of the actuation system. We would always recommend a
preliminary discussion with ZF Electronics.
Please note:
The actuator may not be pre-stressed when at rest. When actuated, the
switch should travel well beyond the switching point. for at least 50 % of
the predefi ned overtravel, in order to ensure that full contact is made.
It is quite unacceptable for the switch to exceed the specifi ed overtravel
or end position. Using the switch as a mechanical end stop should be
avoided. A high-impact actuation of the switch can have a negative effect
on the switch’s mechanical life.

Generally we can produce any switch variant on a customer-specifi c basis.
But we kindly ask for your understanding that this may eventually cause
longer lead-times or the requirement for certain minimum order quantities.
The complete overview of all possible switch variants can be found in
the dedicated technical specifi cation for each product which we will be
pleased to provide you with on demand.
A checklist on the key parameters and requirements to identify the best
suitable product can be found on the fold-out page at the back cover.
Please also make use of this checklist by making a photocopy, fi ll it out
with your requirements and fax it to one of our regional offi ces on the back
cover. We will be pleased to advise you!
Order code
The order code is an 8-digit combination, consisting of letters and numbers
which describes the unique characteristics of a switch.
The following scheme gives an abstract on the composition of the order code:
