Abstract: This device for controlling the operation of a bidirectional DC motor comprises a pair of double-throw control reversing switches and a pair of ON-OFF switches, a solenoid-operated brake associated with the motor shaft, and two pairs of unidirectional elements consisting of diodes. The cathode or anode of each diode is connected directly to the common terminal of each control reversing switch associated therewith and the brake solenoid is connected in parallel with the motor induction windings. The terminals of the brake solenoid are disposed between the motor windings and one of the ON-OFF switches so that the brake is applied as long as its solenoid is deenergized.
