The vandal-proof latching action switch MSM LA from Schurter has been redesigned and is now also available with point illumination. For indicating the switching status or for providing visibility during night-time use, point and ring illuminated versions in red, green and blue are available. Different types of contacts offer a range of permissible switching voltages up to 125 VDC / 250 VAC. All options for the MSM LA are available in single-pole and double-pole versions.

The latching action switch MSM LA is available in 19 and 22 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 switching status is required. The standard type as well as the versions with ring illumination and now also point illumination may be provided with lettering using standard or customer-specific characters. The laser lettering process is carried out in-house.

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. This provides a user-friendly actuating function and also prevents inadvertent switching, e.g. caused by objects leaning on the switch. Due to the stainless steel housing as well as the high impact strength, the switch is particularly suited for use in equipment in harsh environments or for vandal-protected applications.
