  • Safety switches with corresponding keys are known for example from DE-A-3 100 862, 3 209 414, 3 330 109 and 3 433 048.
  • the radius actuator 4 is on a pivotable flap, cover or the like about an axis. (shown in dashed lines) by means of screws at a distance R from the axis of the flap, the cover or the like. attached and has an elongated in the plane of the key 3 holder 5 for the key 3.
  • the holder 5 is received by a cap-shaped cover 6, each on both sides with a corresponding screw hole 7 for a countersunk screw for attachment to the flap, the cover or the like. is provided with the holder 5.
  • the key 3 has a central slot 8 for gripping around an intermediate wall 9 located in the slot 2 of the safety switch 1 and also has extensions 11 carrying wedge surfaces 10 on the side facing away from the holder 5 adjacent to the slot 8.
  • the holder 5 has at its two ends in the plane of the key 3 opposite shaft stub 12. Furthermore, a bottom plate 13 is provided for the holder 5, which has end bearings 14 for the shaft stub 12 (see in particular Fig. 6), so that the Holder 5 is rotatably arranged relative to the base plate 13.
  • the bearings 14 are in the illustrated embodiment on the stub shaft 12, these encompassing more than 200 °, snap-on design, but they can also consist of interconnectable halves, one half being formed in one piece with the base plate 13, while the other half is independent or is formed in the cover 6.
  • the middle part of the holder 5 located between the shaft ends 12 has a continuous radial recess 15 which opens into an axial slot 16 on the side facing away from the base plate 13.
  • a bore is arranged in the holder 5 transversely to the recess 15 and receives a pivot axis 17 about which the key 3 can be rotated in its plane.
  • the key 3 has a central extension 18, which is arranged on the side opposite the extensions 11. The pivot axis 17 is secured against falling out by the cover 6.
  • a compression spring 19 (helical spring) is clamped in the area of the slot 16 between its base and the adjacent lower edge of the key 3 in order to pretension the key 3 into a position pivoted in its plane.
  • the compression spring 19 is expediently clamped at one end to a pin 20 at the bottom of the slot 16.
  • the bore 21 is initially polygonal in section, for example hexagonal, and without a thread.
  • the set screw 22 cuts itself self-locking when screwing in later.
  • the set screw 22 is provided with a hexagon socket 23 and so offset from the slot 16, the width of which is slightly greater than the thickness of the key 3, that the adjusting screw 22 can be adjusted by means of a socket wrench, without the key 3 interfering with it.
