Through microcomputer control, it automatically finds the best switching-in point and the best switching-off point to achieve zero-voltage switching-in and zero-current switching-off. The on-off at the moment is completed by the thyristor, and the continuous current during operation is completed by the magnetic latching relay being triggered by a pulse voltage to make the contacts close.
