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!
