Switching system

The double-break, snap-action switching element is equipped with

one or two independent contact systems, acting as normally open

or normally closed contact. The snap-action switching element is

fitted with self-cleaning contacts.

Up to three switching elements can be snapped to each actuator.

Snap-action switching elements are not permissible for emergency-

stop pushbuttons!
