Summary:This electromagnetic operation mechanism drive circuit is constituted by: a movable iron core (1); a pole-closure driving coil (2) driving the movable iron core (1); a pole-closing capacitor (4) supplying power to the pole-closure driving coil (2); a pole-closure driving switch element (5) controlling the supply of power to the pole-closure driving coil (2); a protection relay (7) provided betweenthe pole-closure driving switch element (5) and the pole-closure driving coil (2); a pole-closing side overvoltage suppression circuit connected in parallel to the pole-closure driving switch element(5) and configured so that a pole-closing side loop circuit switch element (6) is connected in series to a pole-closing side loop circuit (10); and a pole-closing side voltage detection circuit (13)detecting the voltage of the pole-closing side loop circuit switch element (6). In this manner, even if a switch element of a pole-closing side overvoltage suppression circuit in a drive circuit for switching on and off electri
