<p>The apparatus, such as a remotely-controlled breaker, a relay or a timer, comprises an electronic circuit (5) inserted between the control button (4) and the circuit powering the coil (2) in order to direct to the coil a predetermined short-duration driving pulse in response to the random or non-random duration actuation of the control unit (4), the size of the coil (2) being reduced below the value which would permit continuous passage of the motor current. <IMAGE></p> |
