Technical Data
Switching system
This low-level switching system was designed for switching low
powers in electronic circuits. The switching system assures reliable
switching of loads.
Single-break momentary contact, as normally open or normally
closed with 4 independent points of contact.
Special features are the long life, extremely short rebound time and
stable contact resistance.
Contact combinations: 1 normally open contact, 2 normally open
contacts, 1 normally closed/1 normally open contact, 1 normally
closed contact
