A device for opening or closing an electrical circuit by means of a secret combination, variable at will, essentially characterized by the fact that it consists of a plurality of buttons combined with respective relatable jacks so that the current only passes or stops passing through the assembly by them formed when each one of the jacks is placed in a certain position that gives rise to the preset secret combination, the pushbuttons corresponding to the jacks that in such a combination contribute by their position to prevent the closing of the circuit that only occurs when it is derived, are pressed. The passage of the current through such buttons when simultaneously operated. (Machine-translation by Google Translate, not legally binding)
