摘要：
The device is used for the control of an electromagnet of which the coil (L) is connected to an alternating current supply source through a switch (T) controlled by a control circuit. Said control circuit comprises a member for determining the zero voltages of the alternating current (R4, C3, D3, IN1, C4, R6, IN2), a delay element adjusted to obtain a delay time which corresponds to the privileged control angle of the electromagnet and a switching device (FL) controlled by the delay element in order to deliver to the switch (T), following a control order, a control signal retarded by said delay time. The invention applies particularly to contactors and to electrovalves.
