The cylindrical M12 microswitches are used in potential explosive athmospheres zone 1/2, wherever the switching status must be recorded accurately without using an additional intrinsically safe amplifier.

Because of the goldplated contacts, the M12 microswitches can also directly connected to intrinsically safe circuits. Due to the cylindrical design, they can be precisely adjusted by the M12x1 fine thread or can be installed in the usual mounting kits for inductive proximity switches of the size M12.
