B-Series

Essen deinki’s B-Series micro switches are all about precision and dependability. These switches are designed for quick snap-action, making sure they respond precisely in various applications. What sets them apart is the fine silver contacts, ensuring smooth and long-lasting operation. With a beryllium copper trident spring mechanism, they’re built tough for lasting durability.

Wiring is hassle-free with M3 terminal screws, and the 3.96 mm-wide wiring channels are well-protected by a removable insulated cover plate, adding an extra safety layer. They’re reliable and meet the IEC 1058-1 standard, assuring compatibility across different setups. When you need a trustworthy and precise switch, Essen deinki’s B-Series micro switches have you covered.
