Definitions

  • the invention relates to a key switch with the features of the preamble of claim 1.
  • a semi-cylinder lock is releasably attached to the housing cover only from the inside, the lock bit engages behind an intermediate plate in rotational positions outside of a certain rotational position, on which the switch is fixed.
  • the housing cover can be removed with screws accessible from the outside. Only the further opening of the housing interior containing the switch is only possible if one assumes that the housing cover cannot be rotated with the lock in such a way that the screws with which the intermediate plate is fixed to the housing part comprising the housing base are not accessible will. In any case, it is possible for an unauthorized person to loosen the housing cover without a key, so that adverse weather influences can take hold even when there is no further access to the housing interior. Otherwise, this known key switch consists of a large number of components, which requires a corresponding outlay in terms of production technology.
  • the invention has for its object to provide a key switch of the type mentioned, in which an opening of the housing without twisting the lock bit in the particular rotational position is not possible and which is created with a minimum of components.
  • the inventive design of the key switch ensures that the housing can not be opened at all without authorization, so that the attempt to operate the key switch without a key excludes weather influences that can lead to impairment or unwanted switching function.
  • the switch is designed according to the invention so that only two housing parts are required, which accommodate the lock and the switch, so that the manufacture of the switch according to the invention is correspondingly simple and cheap, as far as the required fastening parts are concerned.
  • the housing designated overall by 1, consists of a housing cover 2 and a housing part 4 comprising the housing base 3 (FIG. 3).
  • the housing part 3 comprising the housing base 3 is not shown in FIG.
  • a shield 5 is shown, which overlaps the surface of the housing cover 2 on all sides and is provided in the event that the switch housing 1 is installed in a so-called flush-mounted installation.
  • the housing part 4 comprising the housing base 3 is practically limited to the base 3, that is to say the housing cover 2 encompasses the housing interior 6 almost completely.
  • the housing part 4 comprising the housing base 3 in a pot-like manner, on the outer edge of which the practically flat housing cover 2 can then be placed. Any other parting line between the front surface 7 of the housing cover 2 and the housing base 3 can also be selected.
  • FIG. 1 The top view of Figure 1 on the front 7 of the housing cover 2 shows the external view of the externally accessible end 8 of the profile half cylinder lock 10 used in a formation 9 of the housing cover 2, a rubber sealing plate 11, which is shown in section in Figure 2, has been omitted .
  • the rubber sealing plate 11 has a circular rim and surrounds with a recess the end 8 of the profile half-cylinder lock 10 which is accessible from the outside in close association and is fitted into a correspondingly circular recess 12 in such a way that when the blind shield 5 is screwed on and the pressure exerted thereby is exerted on the rubber sealing plate in sealing contact to the edge of the recess 12 and that of the accessible end 8 of the profile half-cylinder lock 10 is pressed.
  • the shape 9 of the housing cover 2 ( Figure 4) is adapted to the cross-sectional shape of the profile half-cylinder lock 10, so that the lock in the recess 9 is easy to insert and remove without being able to perform significant sideways movements.
  • the depth of the recess 9 is also adapted to the lock 10, although this is not essential, but this reduces the overall height of the switch to a minimum.
  • a bore 15 is provided, through which a screw 16 is guided, which is screwed into a thread 17, which is located in a projection 18 of the housing base 3. The screw 16 is therefore only accessible when the semi-cylinder lock 10 is not in the formation 9.
  • Figures 3 and 4 show that the beard 19 of the lock 10 in the course of its rotational movement in a plane perpendicular to the longitudinal axis of the lock cylinder passes through an opening 20 provided in the side wall of the formation 9 of the housing cover 2 when the lock 10 acts in a rotational position is, in which the lock bit is outside of the rotational position 21, in which it is in alignment within the elongated lock extension 22
  • the lock 10 cannot be removed from the formation 9 because the lock bit 19 engages behind the edges of the opening 20.
  • the lock 10 can only be lifted out of the formation 9 when the lock bit 19 is in a certain rotational position 21, in which it is located within the lock cylinder extension 22 with respect to the lock cylinder profile.
  • the blind hole 30 is guided parallel to the longitudinal axis of the lock cylinder in the installed position and has a hole bottom 31 which is designed to slope downwards with respect to the longitudinal axis of the blind hole 30 towards the housing base 3 and opens laterally into an opening 32 which leads to the hole 29 in the shoulder 22 of the lock profile 10 is aligned.
  • the blind hole 30 and thus the grub screw 28 is covered by the rubber sealing plate 11. Only after removing this sealing plate 11 is the grub screw 28 accessible. If an unauthorized person loosens this screw without having the key for the lock, he can release the lock from the lock, but the lock 10 cannot be removed from the recess 9 as long as the lock bit 19 has the upward edge of the Opening 20 engages in the side wall of the recess 9.
  • the switch designated overall by 25, in the exemplary embodiment shown consists of two push-button elements 33 and 34, which are fixed to the housing base 3 via a projecting projection 35. Between the actuating members 36, only one of which is shown, and the lock bit 1, actuating webs 37 made of elastically deformable plastic are provided, which are held clamped on the housing base 3 or corresponding projections 38 on the latter and which prevent the twisting movement of the lock bit 19 on the actuating members 36 forward the key switch elements 33, 34.
  • the housing cover 2 engages via a sealing lip 39 on the other housing part 4 comprising the housing base 3, so that overall a tight housing formation can be ensured.
  • the electrical supply line is sealingly guided through a cable bushing 40 formed in the housing base 3 or one of the side walls of the housing cover 2, as is known per se.
  • Fastening holes 41 are provided on two diagonally opposite corner regions of the housing base 3, via which the housing can be screwed onto a wall or the like in a surface or flush-mounted installation.
  • the Mi the sealing strip 39 provided edge, which is designed to strive upward from the housing bottom 3, runs in such a way that the fastening openings 41 lie outside the housing, although the basic shape of the housing part 3 having the housing bottom 3 also remains rectangular in the bottom region.
