Description
Both the housing and the actuator of the vandal-proof MSM switch are made of high-quality stainless
steel. Use of this stable and weather-resistant material means that the switch is particularly suitable
for use in harsh environments. The MSM is available with mounting diameters of 16, 19, 22 and
30mm. Different types of contact cover a permissible switching voltage range from 5 to 250 V AC, and
switching currents are permissible from 0.1 to 10 Ampere. The MSM is equipped with flat-pin plugs to
permit fast connection. The cables are plugged onto the micro switch, and this is subsequently
plugged onto the previously screwed-in switch. Point and ring-illuminated versions are available for
applications at night or as an optical status display.
