Abstract:
A safety selector switch for preventing accidental energization of an eleical circuit. A plurality of annular discs, each having a cut-out portion in its periphery, are mounted on a shaft of an electrical component, such as a rotary switch. A second shaft is provided which is translatable in a direction parallel to the longitudinal axis of the shaft of the electrical component, and an arm is provided on said second shaft and is selectively positionable in each cut-out portion of said annular discs to limit rotation of the shaft of the electrical component. Continued rotation of the shaft of the electrical component can only be made by alternately rotating said shaft of said electrical component and translating said second shaft to move said arm to a cut-out portion of an adjacent annular disc.
