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
μ
A/
μ
V up to 100 mA/42 VAC/
VDC.
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.

connection method
The universalterminalspermitthese unitsto be mountedon printed
circuit boards (PCB). These terminals can also be used as solder-
ing 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.
