ABSTRACT:
A circuit interconnecting a source of electrical energy with a power operated machine. The circuit comprises an interlock device including a motion switch which is adapted to be removably attached to the machine operator's body. The motion switch is movable between a normally deactivated position to prevent the flow of electrical energy from the source to the machine and an activated position to permit the flow of electrical energy from the source to the machine for operating the machine. The motion switch is operable to be moved to the activated position in response to movement of the operator's body.
