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.

The non-illuminated version has a translucent white actuating surface. Lettering is black and is applied directly onto the ceramic material. Due to the base material and the lettering process, the lettering is resistant to scratches and to common cleaning agents. In the case of switches designed with illumination, the actuator surface fully illuminates uniformly across the entire surface. Lettering and symbols can also be applied. The standard black lettering provides a positive effect against the illuminated actuator, while negative lettering provides an inverse effect.

The MSM CS is extremely robust and meets vandal-proof demands due to the low profile of the front structure (1.7 mm), the IP 69K protection class and the high level of impact resistance. The switch is available in 19 mm and 22 mm mounting diameters. Different contact configurations are offered over a range of 30 VDC to 250 VAC for the admissible switching voltage; switching currents are permissible from 0.1 to 10 Amperes. The MSM CS is equipped with quick connect terminals to allow for fast connections. The wires are connected to the switching element which is subsequently snapped onto the switch housing.

Schurter’s MSM metal switch series has been extended to include a version with a double pole contact system. The new MSM DP switch is designed with two separate switching contacts. The separate contacts can be used as normally open, normally closed or as change-over. The MSM DP is ideal for potential free momentary switching action of electrical equipment. Furthermore, the switch can be used in applications where an additional second contact is required for a safety circuit. Typical applications are emergency switches where the control loop is switched, and in addition a second circuit for emergency services is activated.

Due to its flat front construction of 1.7 mm, a protection class of IP67 and a high shock resistance, the switch is extremely robust against vandalism. The MSM DP is available in mounting dimensions 19, 22 and 30 mm. The standard type is designed with switching capacities up to 3A / 250 VAC and 5A / 125 VAC respectively. For applications having other switching capacities, alternative variants are available on request. For night applications or where optical status indications are desired, point and ring illuminated versions in different colours are available.
