Description
General notes
The pushbuttons of series 02 are noteworthy for the robust design of
their case, their operational reliability and the large marking and
illuminated area. The pushbuttons contain one or two separately
operating snap-action switching elements.
Switches with free choice of bezel
The free choice of bezel enables users to match switches to suit
different purposes. These bezels protect against unintentional
switching. Standard bezels can be optained in black.
Mounting
The switches, which are pushed into the opening in the panel from the
front, are fixed with a plastic sleeve with a maximum effort of 20 Ncm.
Lenses
The flat lenses, made of polymethyl methacrylate, are obtainable in
various colours, as well as transparent and translucent. All lenses can
be exchanged without affeccting the switch position.
Marking
For further information about engraving, hot stamping and film inserts
see part Marking.
Illumination
The T6.8 incandescent (filament) lamp (6...48 V, 1.2 W) ensures perfect
illumination of the lenses, which are supplied in various colours.
T6.8 Single-LED (6, 12, 24, 28, 48 V) are also available in blue, green,
red, white or yellow.
Luminosity and wave length scattering caused by the technology used
in the LED manufacturing processes may lead to visual differences in
our products.
For supply voltages above 48 V, it is necessary to use a voltage
reduction element (external series resistor or transformer).
Keylock switch
Standard lock number is YB1. If the lock number is not specified, we will
supply standard number YB1.
Additional 9 lock numbers are available on request.
Two keys are supplied with each keylock switch.
Spare keys for standard locks may be ordered by quoting Typ-Nr.
02-989.
Number structure
Nomenclature in accordance with ' IEC 61058 TEST REPOR T '. The
certification document we dispatch to them on demands.

Application guidelines

03.2009
When switching inductive loads such as r elays, DC motors, and DC solenoids, it is always important
to absorb surges (e.g. with a diode) to protect the contacts. When these inductive loads are switched
off, a counter emf can severely damage switch contacts and greatly shorten lifetime.
Fig. 1 shows an induct ive load with a free-wheeling diode connected in parallel. This free-wheeling
diode provides a path for the inductor current to flow when the current is interrupted by the switch.
Without this free-wheeling diode, the voltage across the coil will be limited only by dielectric break-
down voltages of the circuit or parasitic elements of the coil. This voltage can be kilovolts in amplitude
even when nominal circuit voltages are low (e.g. 12 VDC) see Fig. 2.
The free-wheeling diode should be chosen so that the reverse breakdown voltage is greater than the
voltage driving the inductive load. The DC blocking voltage (VR) of t he free-wheeling diode can be
found in the datasheet of a diode. The forward current should be equal or greater than the maximum
current flowing through the load.
To get an efficient protection, the free-wheeling diode must be connected as close as possible
to the inductive load!

General notes
1. Engraving
In addition to the most commonly used world
languages, in DIN 1451-3 close spacing, other
typefaces are available as Scandinavian,
Slavic, Greek, Russian and Polish.
Red, blue and black lenses are filled with white
colour. Other colour lenses are filled in black.
Standard height of letters is 3 mm. If the height
is not specified, we will supply 3 mm engraved
letters.
2. Hot stamping
For larger series it is worth considerin g
markings by means of hot stamping We will
pleased to advise you.
For letters and figures, typefaces with 2.5 mm,
3 mm and 4 mm are available.
3. Film inserts
Instead of using engraving the lenses can be
fitted with transparent film inserts, as an
alternative. For this purpose, though, it is
advisible to use lenses without ripped pattern.
In the case of use of a smoke-black lens the
fitted film becomes readable only if the lamp is
on.
The film (F) is inserted in the cap. To ensure
even illumination a diffusor (D) is
recommended, which is inserted beneath the
film. If, on the other hand, the diffusor is
inserted above the film, the lettering only
becomes legible when the lamp is alight. To
hold the film and diffusor in position, the use of
a holder (N) is advised.
The film thickness is 0.2 mm.
