The new MSM Series switch is capable of powering over a voltage range of 5 Vdc to 250 Vac and a current range of 0.1 to 10 A. With a water-resistant rating of IP67, the MSM is ideally suited for harsh environments and equipment often exposed to liquid spills, drips, leaks, or wash-downs. The unit’s IK07 shock-resistant rating ensures that it can withstand applications where the switch will be subjected to heavy use or impact. Available in three sizes with mounting diameters of 16, 19, and 22 mm, the switch can operate in temperatures ranging from –25° to +85°C. A 1.7-mm flat-front construction enables nearly flush mounting to the panel surface, reducing the chance that the switch will be knocked or battered from the side. The MSM consists of a detachable contact module with a high-grade stainless steel housing and actuator to facilitate smooth acceleration. The switch provides an actuation force of 4.5 Newtons and contact travel of 1 mm with a fixed stop and audible click. Switching action is single-pole, momentary with normally open and normally closed contacts. The MSM is available with point or ring illumination for applications with dim light and for visual status indication. Laser lettering is also available. Applications include point of sale and point of information terminals, access control and security systems, vandal-protected equipment in public areas and large industrial plants, controller panels for automated machinery, construction machinery, and medical equipment.
