Metal Switches with High Resistance to Destructive
Elements, Fully Illuminated Actuating Surface

The new MSM CS metal switch from SCHURTER is equipped with an actuator made of highly durable ceramic. Ceramic is a new technology employed in the production of an electro-mechanical switch.  The new switch provides novel features that open up entirely new areas of application. The actuator material of the MSM CS is resistant to scratches, abrasion, impact and chemicals.
