Switching system:
Low-level element
Switching system:
This low-level switching element was designed for switching low powers in electronic circuits. The mechanism assures reliable switching of loads ranging from a few μA/μV up to 100 mA/ 42 VAC/DC.
Single-break momentary contact, as normally open or normally closed with 4 independent points of contact. 2 momentary contactsper switching element; combination of normally open and normally closed is possible.
Special features are the long life, extremely short rebound time and stable contact resistance.
Release type:
Twist to unlock
Mechanical lifetime:
1 Mil. cycles of operation (RCC/RPB)
Operating force:
18 … 21 N (depending on the switching element)
Operating Travel:
3 mm
Tightening torque:
Fixing nut max. 0.5 Nm
Terminal details 1:
The universal terminals permit these units to be mounted on printed circuit boards (PCB). These terminals can also be used as soldering or plug-in terminals.
For these terminals we can also supply a plug-in base which, when soldered on to the board, enables the switch to be plugged in.
