Patent ID: 6966781

Claim:
An electromechanical connecting device having a switching mechanism which can be connected via power supply contacts to a current source, an operating slide including coded magnet parts, a housing enclosing the operating slide in a closed assembly, the switching mechanism connected to a tripping mechanism which includes tripping magnets having additional coded magnet parts, the tripping and switching mechanisms including contact elements adapted to be connected electrically to a consumer, whereby connecting the two mechanisms in axial alignment brings the switching magnets from a rest position into a working position against a retaining force and completing the electrical connection between the switching mechanism and the tripping mechanism through contact elements disposed in the switching mechanism and the tripping mechanism, the switching mechanism and the tripping mechanism each being provided on mutually facing end faces with corresponding centering elements, the switching mechanism and the tripping mechanism toward the switching mechanism, the electical connection between the switching mechanism and the tripping mechanism made in only a specific position of the coded magnet parts and additional coded magnet parts relative to each other; one of the mechanisms including at least one projection, the at least one projection including an elevation which rises above the projection and is adapted to mate with a correspondingly positioned through in the end face of the other mechanism; the projection constructed as a bulging partial annular bead disposed on one of the end faces and, when the electrical connection is made, is situated in a partial annular groove disposed on the end face of the other mechanism, and which groove corresponds in shape and position to receive the bulging partial annular bead.
