Technical data
Actuator with snap-action switching element
Switching system
Self-cleaning, double-break snap action switching system
(withcontact gap 2 x 0.5 mm).
1 normally closed and 1 normally open contact per element.
Snap-action switching elements with soldering terminals at the
sides: up to 4 switching element can be on a pushbutton
(max. 4normally closed and 4 normally open contacts).
Snap-action switching element with axial plug-in terminals 2.8 mm
is not stackable, only 1 switching element can be on a pushbut-
ton.
