   The position in which the device and the lead wires are attached, of course, changes depending on the purpose for which the device is used, and therefore the structural details and those of the usage instructions may differ somewhat from what has been described above, without, however, going outside the scope of the invention to fall. PATENT CLAIMS:

 clock (F, L) the alarm bell or the like is switched on in the electrical line.

Claims

2. Device according to claim 1, characterized in that it comprises a forked lever with lugs (P) and a lever (G) actuated by a special key (dol) which in the rest position also has the forked lever (N) in the rest position holds, in which he keeps the contacts (F) from the mating contact (L) and fixes the pin (R, U), whereas in the preparation position the control lever (G) releases the forked lever (N), but the latter only then in the working position is reached when it is pushed back by the pin (R, U) by opening the door or the like.

3. Device according to claim 2, characterized in that the lever (G) has two notches (W) in order to hold it temporarily in the respective position by a spring (X).

4. The device according to claim 1, characterized in that the contact lever (F), the control lever (G) and the locking lever (V) in a housing (C) with a keyhole are rotatable about mutually parallel axes.

5. Device according to claims 1 and 2, characterized in that the under the action of a spring (1) standing pin (R) with a transverse pin (R1) is between the prongs of the forked <Desc / Clms Page number 3> Lever (N) extends through and through an opening in a transverse wall of the housing (0) and extends against an inward contact when the door or the like is pressed through the door frame or the like.
