Self-cleaning, double-break, snap-action switching elements (con-
tact gap 2 x 1.5 mm).
The elements can be supplied with the following choice of switching
functions:
for illuminated pushbutton or switch actuator with 2 positions:
max. 2 normally open contacts, max. 2 normally closed contacts or
combined
for 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.
