An electronic control apparatus applicable to a number of different actuatable structures of the type requiring a predetermined voltage level or current flow wherein the apparatus utilizes a decoding means having a plurality of current-carrying elements which are arranged in a manner so as to require simultaneous actuation in order to provide a desired enabling voltage or current flow for the structure with which the apparatus is connected. The apparatus is especially adapted for use as a lock for a system having an ignition coil for energy transfer between the windings of the coil can be effected only if the elements of the decoding means are simultaneously actuated.
