Abstract
A reversible rotary shampoo machine or floor waxer is provided which consists of a reversible motor and a reversing switch having a safety off position electrically connected in a circuit to the reversible motor, with the reversing switch mechanically interlocked to the on/off switch so that the on/off switch must turn off the motor before the reversing switch is permitted to change the direction of rotation of the reversible motor, in order to prevent damage to the reversible motor, or accidental injury to an operator.
