Expanding its MSM family of metal pushbutton switches, Schurter has introduced a new model that is equipped with an actuator made of rugged ceramic. The material is resistant to scratches, abrasion and impact as well as chemicals, making the unit suitable for many medical technology applications. If the switch is not illuminated, the actuator surface remains white. Standard or customer-specific lettering is embedded directly in the ceramic material.
In the illuminated versions of the switch, the actuator face is lit up across the entire surface; lettering and symbols can be applied. Positive lettering is done in black; in the case of reverse lettering, the text appears in the selected colour. The labels are scratchproof and withstand common cleaning agents.
Thanks to a low-profile 1.7-mm front mount, IP69K rating and impact resistance, the switch is extremely robust. The MSM CS is available in 19- and 22-mm mounting diameters. Various contact types cover a range of switching voltages from 30 V dc to 250 V ac; allowable switching currents range from 0.1 to 10 A. For fast wiring, the MSM CS is designed with blade terminals. Wires are connected to the microswitch element, which is snapped onto the screwed-in switch housing.
