Technical data
Actuator with low-level switching 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
contacts
per 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.
Material
Material of contact
Gold plated
Switch housing
Plastic, heat-resistant and self-extinguishing
Actuator housing

Mechanical characteristics
Terminals
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.
