Technical Data
switching system
material
mechanical characteristics
actuator with snap-action switching element
Self- cleaning, double-break, snap-action switching elements (con-
tact gap 2 x 0.5 mm).
The elements can be supplied with the following choice of switching
functions:
for illuminated pushbutton or switch actuator with 2 positions: max.
3 normally open contacts, max. 3 normally closed contacts or com-
bined
switch actuator with 3 positions:
max. 2 normally open contacts, max. 2 normally closed contacts or
combined
The switching element can be easily snapped to or dismantled from
the actuator.
