Abstract:
An interlocking device that prevents simultaneous throwing of at least two switch actuators, comprising:a support surface; a pair of switch actuators mounted on said support surface in lateral relation to one another; each switch actuator of said pair of switch actuators having a down position and an up position; an elongate locking bar having two laterally spaced apart switch actuator-receiving recesses formed therein; said elongate locking bar being slideably mounted relative to said support surface for lateral displacement in closely spaced relation to said pair of switch actuators; said elongate locking bar having a first position where a first switch actuator receiving recess is in alignment with a first switch actuator so that said first switch actuator can be thrown; a second switch actuator recess being misaligned with a second switch actuator when said first switch actuator recess is in said alignment with said first switch actuator; said elongate locking bar having a second position where said second switch actuator receiving recess is in alignment with said second switch actuator so that said second switch actuator can be thrown; said first switch actuator recess being misaligned with said first switch actuator when said second switch actuator recess is in said alignment with said second switch actuator; whereby said elongate locking bar prevents simultaneous throwing of said pair of switches.
