New Metal Pushbutton Switches with Ceramic Actuator Face

This new model with a patented ceramic actuator face expands SCHURTER’s MSM family of metal pushbutton switches with rugged background illumination over the full actuator surface. The material is resistant against scratches, abrasion and impact as well as chemicals and makes the unit well suited for many applications in medical technology and industry.

The new MSM CS metal pushbutton switch from SCHURTER is equipped with an actuator made of rugged ceramic. Ceramic is being employed for the first time in an operating switch and is patented by SCHURTER for this application. The material is resistant against scratches, abrasion and impact as well as chemicals; it can also be labeled and is translucent. Equipped with these versatile features, the MSM CS pushbutton switch opens up completely new possibilities in the construction of medical equipment and in industry.

If the switch is not illuminated, the actuator surface is white. Standard or customer-specific lettering is in black and embedded directly into the ceramic material.

In the illuminated versions of the switch, the actuator face fully illuminates across the entire surface, and lettering and symbols can also be applied. Positive lettering is done in black; for inverse lettering, the label text appears in the selected illumination color. Because of the way they are made, the labels are scratch-proof and stand up to common cleaning agents.

Thanks to a small, low-profile front mounting of 1.7 mm, the IP69K protection class and high level of impact resistance, the switch is extremely robust and protected against vandalism. The MSM CS is available for mounting diameters of 19 and 22 mm. Various contact types cover a range for allowable switching voltages from 30 VDC to 250 VAC; allowable switching currents range from 0.1 to 10 A. For fast wiring, the MSM CS provides blade terminals. Wires are connected to the microswitch element, which is subsequently snapped onto the previously screwed-in switch housing.
