Bench drill control circuit

The utility model discloses a bench drill control circuit. The bench drill control circuit comprises a power supply switch; the power supply switch is connected with a driving motor respectively via a forward alternating current contactor and a reverse alternating current contactor; the power supply switch is connected with a step-down?transformer; one end of the low-voltage side of the step-down?transformer is connected with a foot switch; the foot switch is a single-pole?double-throw?switch; two double-throw ends of the foot switch are respectively connected with a reversing switch; the reversing switch is a double-pole?double-throw?switch; one end of the reversing switch is connected with a forward coil and a reverse?normally-closed switch, and the other end of the reversing switch is connected with a reverse coil and a forward normally-closed switch; the reverse?normally-closed switch and the forward?normally-closed switch are both connected onto the other end of the low-voltage side; the forward coil is
