This low level switching element was designed for switching low
powers in electronic circuits. The mechanism assures reliable swit-
ching 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 of contact
Gold plated
Switch housing
Polysulfone, heat-resistant and self-extinguishing
Actuator housing
Polyetherimide, self-extinguishing
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.
Soldering terminal:
Max. wire diameter 2 wires à 0.8 mm
Max. wire cross-section of stranded cable 1x 0.75 mm²
Plug-in terminal 2.0 x 0.5 mm
Actuating torque
2.5 Ncm ... 5.5 Ncm, measured at the key or lever of the keylock- or
selector switch
