Technical Data
Switching system
Self-cleaning, double-break snap-action switching system with
contact opening width 2 x 0.5 mm (switch with small contact
opening width as per EN IEC 61058-1).
The switching elements are optionally equipped with the following
switching functions :
One to three normally open (NO) or normally closed (NC), or any
combination of NO and NC plus connections for T1
