ABSTRACT:
A device for actuating a warning device includes a contactor for actuating an electric circuit of the warning device, which contactor is operated for switching-in by means of a movable touch pin, which touch pin, by means of a spring force acting thereon, follows the relative movement between a fixed point and a point belonging to a door leaf, a window or the like, so that when the distance between these two points is increased, the touch pin moves so much that the contactor is operated into its switching-in position. In order to form a small unit, which can be built-in into the conventional securing plates of doors, windows and the like, the touch pin is connected with a catch, which in its catching position holds the touch pin in a fixed position, at least against movements in the direction in which the spring force acts. The catch is controlled by a lock plunger bolt or by the corresponding movable parts of a lock for a door, window and the like, in order to be held firstly in its catching position and secondly in a position in which the touch pin is released.
