ABSTRACT:
A controlling circuit for an actuator which is provided with a change-over switch for selecting a desired rotational position of a rotating shaft of the actuator, exciting circuit forming device for selectively magnetizing a plurality of electro-magnets in order to control rotation of the rotating shaft to be in a selected desired rotational position in response to an outputted change-over signal, and electrifying switching device for supplying electricity to the electro-magnets only for a predetermined duration from the time when selection of the rotational position of the rotating shaft is changed over by the change-over switch, wherein there is no generated any unnecessary heat for the actuator and construction of the circuit can be more simplified.
