Description

Die Erfindung hat den Zweck, einen Stromschluß nur mit einem passenden Schlüssel zu ermöglichen. Erreicht wird der Zweck durch eine nach Art der bekannten Sicherheitsschlösser ausgebildete Vorrichtung. Diese ist in den Abb. ι bis 3 in drei zueinander senkrechten Ansichten dargestellt.The invention has the purpose of a power supply only with a suitable key enable. The purpose is achieved by a type of the known security locks trained device. This is in Figs. Ι to 3 in three mutually perpendicular Views shown.

Die durch den Schlüsselbart gehobenen, aus isolierendem Material bestehenden Plättchen α drücken die Kontaktfedern b gegen Kontaktfedern c, wenn der Schlüssel nach rechts gedreht wird. Nur wenn sämtliche Kontaktfedern des in der Zeichnung mit vier Sperrungen ausgeführten Sicherheitskontaktes geschlossen sind, kommt Stromschluß zustande, da der Strom alle Federn hintereinander durchfließen muß.The raised by the key bit, consisting of insulating material plate α press the contact springs b against contact springs c when the key is turned to the right. Only when all the contact springs of the safety contact, which is shown with four locks in the drawing, are closed does a current connection occur, since the current must flow through all springs one after the other.

Patent-Anspruch: Patent claim: Elektrischer Sicherheits-Schlüsselkontakt, gekennzeichnet durch mehrere, durch die Bartstufen eines Schlüssels verstellbare Organe (α), die auf je einen von mehreren hintereinander geschalteten Kontaken (fr, c) derart einwirken, daß die Kontakte nur dann sämtlich geschlossen werden, wenn jede Bartstufe die zur kontaktbildenden Verstellung des zugehörigen Organs erforderliche Höhe besitzt. Electrical security key contact, characterized by several organs (α) adjustable by the beard steps of a key, which act on one of several consecutive contacts (fr, c) in such a way that the contacts are only all closed when each beard step the has the required height for contact-forming adjustment of the associated organ. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
