UP TO 10 (1,5) A 250 V~
PRODUCT ADVA NTAGES
◆Small snap action switches in size
DIN 41635 design B
◆Maximum functional reliability by ten-
sion spring contact system
◆Precise switching accuracy with long
life endurance
◆Special shape of the PCB terminals for
better automatic soldering
◆The versions with mushroom-head
actuators can be approached from all
sides
◆The standard program includes a
number of different ratings and
terminal versions
◆The optional actuators made of
chrome-nickel-steel are available in dif-
ferent shapes and lengths. These can
easily be retrofitted.

The mushroom head actuator allows actuation
from all sides in addition to vertical actuation
from above.
An angle of < 45° is necessary on the actuating
element for such applications (angle for versions
with longer over-travel on request). To keep the
friction as low as possible, we recommend that
you use materials with a low friction coefficient.
The surface of the actuating element should be
polished.
The mechanical life depends on the material
and surface properties as well as on the design
of the slide.
