Ceramic Surface Brighter on Metal Switches

SCHURTER’s MSM series offers an even more attractive metal switch, with brighter and richer colors illuminating from its ceramic surface. The first of its kind metal pushbutton is now offered with a rich green, red, or blue illumination, as well as bright white. The MSM CS is momentary action, and the MSM LA CS is single or double-pole latching action.

Ceramic is a durable material, which is highly impervious to damage. Used as a switch actuator for the MSM CS and MSM LA CS, it is ideal for applying laser lettering or symbols, resistant to scratches, abrasives and chemicals. The ceramic actuator and stainless steel housing are also rated IK07 impact resistant. The MSM CS has an ingress protection rating of IP65 from the front, or IP68 with protective cover. The MSM LA CS is rated IP64 from the front contact area. Two different sizes include mounting diameters of 19 mm and 22 mm.

The multi-faced MSM switch series offers metal actuators in addition to ceramic. Metal actuators feature point and ring illumination. Rated 0.1-10 A and 30 VDC to 250 VAC for the momentary types, and up to 16 A at 250 VAC for the latching action types, the series is equipped with various microswitch options. Options for LED supply voltage are 5, 12 & 24 VDC for the momentary types, and 24 VDC for the latching action types.

Applications for robust illuminated switches include ticketing and vending machines, sanitation controls, access controls, and industrial control panels. Versions with protective cover are suitable for equipment in food service and processing industries. The aesthetics of the MSM CS and MSM LA CS, with surface backlighting, appeal to pro audio equipment designers, as well as designers of other high-end home or commercial appliances.
