Technical Data Series 61
Actuator with snap-action switching element
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 3/4 LED or lamp.
The number of switching elements cannot exceed three.
The switching elements provided for the 3-position switch actuators
are equipped with max. 2 NC or 2 NO or any combination. The number
of switching elements cannot exceed two.
