Relays with forcibly
guided contacts
2
Depending on the type of relay, our
production sequences are fully or
partly automated, whereby highest
quality is also guaranteed in the few
manual operations. All products are
made exclusively at our factory in
Bad Ragaz, Switzerland.
The company
ELESTA relays GmbH established in
the Swiss town of Bad Ragaz is one
of the leading producers in the field
of safety relays with forcibly guided
contacts. A very comprehensive pro-
gramme of safety relays enables
ELESTA relays to offer the right
product for just about all application
areas.
Specializing in relays with forcibly
guided contacts, ELESTA relays
impresses its customers and the
market over and over again with
innovation which sets distinct bench-
marks in the world of safety relays.
Products
Relays made by ELESTA are used in
safety applications all over the world.
The application areas are highly
diverse and range from e.g. emer-
gency-off switching devices over
transport systems (lifts, escalators,
etc.) right to complex machine con-
trols. The focus is on ELESTA relays
wherever humans and expensive
equipment need to be protected
from injuries and damage, respec-
tively.
ELESTA relays attaches great
importance to quality. With a rigid
quality programme applied during
the entire production process and
100% inspection before delivery we
combine “Safety without compro-
mises“ and “Quality without com-
promises“.

Safety requirements
Relays with forcibly guided contacts
are used in safety-oriented applica-
tions for the decoupling of differ-
ent voltage potentials. These relays
permit implemention of self-moni-
toring systems. Complying with
the European standard EN50205,
a relay with forcibly guided con-
tacts consists of at least one N.C.
and one N.O. contact. Break and
make contact must never be closed
at the same time during the entire
life of the relay. In case of a fault
the contact gap must be at least
0.5 mm. Additionally, the insula-
tion values are subject to higher
standards and pollution degree 2
is defined for relays with forcibly
guided contacts. For the contact
spring assemblies and other con-
ducting parts in the relay it must be
ensured that no short circuits or con-
ducting connections result in case
such parts should ever fracture or
become loose.
Our strengths
As an acknowledged specialist in
the production of relays with forci-
bly guided contacts ELESTA relays
offers its customers a comprehen-
sive range covering virtually all appli-
cation cases. Permanent observa-
tion of the market, the participation
in standardization committees and
a close cooperation with suppliers,
research institutions and directly
with the users enable us to offer
our clientele innovative products
to suit their requirements in good
time. With our outstanding custom-
er support, high flexibility and on
time deliveries we provide the serv-
ices which buyers of such products
rightly expect. Our strengths are:
• Relays for switching currents from
5mA to 16A
• 2 to 10 contacts
• Minimum coil capacities
• Minimum space requirements
• Wide coil working ranges
• High insulation values
• Customized relay variants
• RoHS-conforming and safe at higher
solder process temperatures
• Reliable and rapid support
• Short delivery times

Customer value
With ELESTA relays, however, the
high quality is not only reflected in
the products. Our maxim must stand
up to highest demands also in the
close cooperation with our custom-
ers. The majority of our deliveries,
for example, are shipped within one
week from receipt of the order, and
we promise to deal with your techni-
cal enquiries within 24 hours.
An intensive cooperation with our
customers is very important to us.
Our specialists are ready to support
you in the choice of the correct
relays for your application, train your
personnel in matters of safety relays
and make their know-how available
to you in complex cases.

Gold contacts with 4-6μm layer thickness
When high voltages and currents are
switched, the layer of gold is destroyed
already after a few switching operations.
Once the gold layer is damaged due to the
switching of high loads, such a contact must
not be used any more for signal and control
current circuits.
Safe contact making is then only possible at
high loads with the formation of sparks.

Certificate of environmental compatibility
Compatibility with the environment is of particular importance to ELESTA relays GmbH.
All materials we process, the consumables, packaging products, cleaning agents etc.
we use have been selected with a view to their eco-friendliness already for many
years. Careful handling of the natural resources, lowest possible energy consumption,
pendulum systems for input and auxiliary materials as well as optimized recycling
processes are a matter of course for us. They extend far beyond what legislation
demands.
Conformity with the EU guideline 2002/95/EG of 27 January 2003
(RoHS)
Our products comply with the legal requirements according to the EU guideline
2002/95/EG dated 27 January 2003 (RoHS: Restriction of Hazardous Substances).
None or our products contain any of the substances listed below:
• Lead, mercury, cadmium, hexavalent chromium
• Polybromated biphenyle (PBB), polybromated diphenyle ether (PBDE)
Soldering processes and suitability for the process
Our products are suitable for all common soldering processes based on higher
temperatures. It is the user‘s responsibility, however, to check and confirm the
suitability for the particular process in the individual case.
Application consultancy
ELESTA relays GmbH offers its customers comprehensive application consultancy also
in the context of the RoHS directives and the environmental compatibility of ELESTA
relays products.

Quality without compromises
Being specialized in the production of safety relays,
we protect humans and equipment alike and assume
a particular responsibility for our products. Every
employee of ELESTA relays GmbH is aware of this
obligation in his/her daily work. In numerous recorded
inspection steps from the incoming materials over
the production process with 100% checking right to
dispatch we guarantee the safety and product quality
required for relays with forcibly guided contacts –
for the benefit of man and machine!
Production mostly on the premises, sophisticated
equipment and an experienced as well as highly
motivated workforce ensure that our products are of
highest quality. Extremely short delivery times are
possible thanks to highly flexible order processing,
even when special coils and customized relay varia-
tions or supplies of samples and pilot series are con-
cerned.
It is a matter of course for us to develop products
with and for our clientele. In this way we guarantee
that our customers get the right products for their
specific applications.
Our innovation leadership in relays with forcibly guided
contacts is evident in the development, production,
logistics as well as the selection of available relays
and our competent application consultancy – for the
benefit of our customers!
Our process-oriented management system guarantees
flat structures and short decision making. Continuous
improvement processes, further education, contribu-
tion to standardizations and close contact to custom-
ers and suppliers are firmly in place. „Swiss Quality“
is a reality at ELESTA relays GmbH.
