  • the mechanism of the defined displaceability of the switching component 40 relative to the housing 20 corresponds to that of DE 31 45 803 C2 and is only briefly explained.
  • a pin 36 which extends through the bottom 44 of the switching component 40 and on his End carries a bolt 37 which is rotatable on the pin 36 but axially immovable is stored.
  • the bolt 38 acts with a tooth having different depths Cam surface 39a in the bottom 44 and with a formed on the underside of the holding part 80, toothed cam surface 39b (Fig. 3) together.
  • the overall mechanism that determines the two defined switch positions of the switch is known per se and will not be described further.
  • the described switch is assembled as follows:
  • the bottom part 28 with the contact tongues 30 and contact tracks 32 is over the pin 36 and the bolt 38 are joined to the switching component 40, so that by the relative movement of the two components conditional switching function of the switch is given.
  • the fully assembled printed circuit board 86 is inserted into the holding part 80 96 provided, inserted.
  • the light-emitting arranged on the top of the holding part 80 Diodes 94 are optionally connected to the printed circuit board 86 via the connecting wires 96 connected.
  • a pre-assembled assembly is created, the electromechanical or large-scale one Protective components of the circuit between the circuit board 86 and the cover 93 takes up and the rest of the printed circuit with other electronic components, for example integrated circuits, between the circuit board 86 and the bottom 88 of the Holding part 80 securely protected.
