Abstract: A control assembly for a reversible motor operating a drive wheel in a wheel spinner used for vehicle wheel balancing or the like including a power switch for actuating the motor when the drive wheel is moved into engagement position with the vehicle wheel and a reversing switch for selectively reversing the direction of rotation of the drive wheel. The control assembly includes locking structure for the two switches so that a polarity to the motor cannot be changed with the power switch in a closed condition and the power switch cannot be closed with the reversing switch in an intermediate condition. A brake is also provided for the drive wheel when returned to its non-engaging position to stop the motor before the motor polarity can be reversed.
