<p>An electromagnetic repulsion driven switch in which a closing coil (19) and an opening coil (20) are oppositely so arranged as to face a conductive repulsive member (18), any selected one of the coils (19, 20) is charged with driving current supplied from a capacitor (24) which is charged to a prescribed charge voltage by a charging power supply (22), and a fixed contact (15a) is separated from or brought into contact with a movable contact (15b) by the repulsive electromagnetic force generated between the coil (19 or 20) and the repulsive member (18). The switch has voltage control means (30) for controlling the output voltage of the charging power supply (22) so that the peak value of the driving current may be within a prescribed range even when the temperature of the capacitor (24) changes. Thus, even if the temperature at which the capacitor (24) is used changes, the driving current values of the coils (19, 20) can be within a prescribed range.</p> |
