The invention relates to an electric push button which allows electricity to flow using one key. It comprises a key, with orifices, which on insertion into its mortice 44 allows the displacement of an insulating plate 16 in which metal pieces 7, 8, 9, 10 are inlaid which function as breakers with terminals 18, 19 and the key. The metal pieces 7, 8, 9, 10 are connected up with cables to a two-relay circuit. If the orifices of the key coincide with the orifices 24, 25 of its mortice 44, proper operation of the circuit of the relays is produced thus providing the electrical supply to an apparatus or to a circuit. Among the most interesting applications of the invention may be cited the private use for turning on electric or electronic circuits or electric locks. <IMAGE>
