Both, the housing and the actuator of the vandal-proof latching action switch MSM LA are made of
high-quality stainless steel. By using this robust and weather-resistant material and due to the
high impact resistance, the switch is particularly suited for use in equipment in harsh
environments or for vandal-protected applications.
element which is subsequently plugged onto the previously screwed-in actuating element.
Point and ring illuminated versions in red, green and blue are available for indicating the switching
status or for providing visibility during night-time use. All versions can be lettered. All options for
the MSM LA are available in single-pole and double-pole versions.

The MSM LA is available in 19 and 22 mm mounting diameters
and suitable for use in temperatures ranging from -40 °C to
+85 °C. With an actuating travel greater than 5 mm, the MSM LA
is ideal for use in applications where increased feedback of the
switching status is required. Different types of contact offer a
range of permissible switching voltages up to 125 VDC / 250
The switching status (ON/OFF) is easy to discern by looking at, or
feeling, the resting position of the actuator. In the off state, the
actuator position protrudes from the housing; in the ON state, it is
depressed into the housing.
The MSM LA is equipped with quick connect terminals to allow for
fast connections. The cables are plugged onto the switching
