The switch (5) is inserted in a cylindrical cartridge (1) with an external thread partly covering its surface. The cartridge is fixed on a support between two nuts (8). A connection cable (11) is attached to the switch extremity (9) via a bent connector (10). The cartridge also accomodates an oscillator connected to the switch and has a coil (12) fixed in moulded plastic.
