Abstract (en)
[origin: US4578734A] The invention relates to an electronic device controlling the electromagnet of a multiple operation electrical apparatus. The electromagnetic coil (14) is connected in series to a triac (25) regulated by a generator (32) associated with a monostable flip-flop (34) designed to supply a single pulse of time-length T at each order from a logic circuit (36). A selector (38) cooperates with each output S1, S2, S3 . . . of the logic circuit (36) to choose a predetermined mode of operation of the apparatus (10), particularly remote-operated switch, contactor, or ON-OFF mode.
