Technical data
Slow-make switching element
Switching system
The double-break, slow-make switching element is equipped with
one or two independent contact systems, acting as normally open
or normally closed contact. The normally closed contact has
forced opening.
Slow-make contacts with forced action are ideal for high switch
ratings.
Up to three switching elements can be snapped to each actuator.
For the emergency-stop pushbutton use the slow-make switching
element (max. 2).
