S-Series

Essen deinki’s S Series micro switches are all about reliability and toughness. These single-pole changeover switches snap into action quickly, making sure your operations are spot on. They’ve got fine silver contacts, which means they work smoothly and last a long time. Plus, the beryllium copper trident spring inside ensures durability.

Wrapped up in a sturdy metallic casing, these switches can take a beating, so they’re perfect for rough environments. They even offer protection against dust, physical jolts, and accidental splashes. Wiring is a breeze with M3 screw terminals tucked neatly into 3.96 mm-wide channels, and there’s an insulated cover plate for added safety.

These switches meet the IEC 1058-1 standard, assuring you of their compatibility and reliability in different applications. When you need a dependable and rugged switch, Essen deinki’s S Series has your back.
