An electrical circuit for a switch having a lockout feature is described. The circuit permits both a primary operator and an auxiliary operator to operate a bi-directional motor by activating separate low-current switches. The circuitry enables the primary operator to disable the auxiliary operator's ability to operate the motor by activating a lockout switch. With the lockout switch activated, the primary operator can operate the motor without interference from the auxiliary operator. High-current power switches, activated via logic circuitry rather than by the operators, are used to complete a power circuit for energizing the motor. |
