ABSTRACT:
A device for randomizing the operation of an electrical switch such that it can be used to switch electrical devices at random time intervals. This device uses a mechanism which periodically disconnects a drive train from a motor, randomizes the position of the drive train, and uses the resultant position of the mechanism to trip an electrical switch.
