PRODUCT DESCRIPTION
Both, the housing and the actuator of the vandal-proof MSM DP switch are made of high-quality
stainless steel. By applying this robust and weather-resistant material, the switch is particularly
suitable for the use in harsh environments. Furthermore, the switch can be used in applications
where an additional second contact is required for a safety circuit.
The MSM DP is available with mounting diameters of 19, 22 and 30 mm. The switch is equipped
with two separated switching contacts which are available as normally open, normally closed or as
change-over. Different types of contact cover a range of permissible switching voltages from 30
VDC to 250 VAC, switching currents are permissible from 0.1 to 10 Ampere. The MSM DP is
equipped with flat-pin plugs to permit fast connection. The cables are plugged onto the micro
switch which 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.
