Abstract
A parts gripper having a continuity switch to determine the presence of a part or workpiece held between the jaws of a parts gripper comprising a parts gripper having a yoke, a pair of jaw members, a pivot pin, a cover plate, a side impact plate, and an electrical lead conductively connected to the first attachment portion of the pivot pin. The pivot pin is conductively connected to the jaw members and connects the jaw members to the yoke of the gripper body. The pivot pin includes a shaft, a neck portion, a stepped portion, and a first attachment portion. The shaft connects the jaw members to the yoke. The cover plate has a keyed through-hole for mating with the neck portion of the pivot pin. The side impact plate has a slot for mating with the stepped portion of the pivot pin to prevent the pivot pin from rotating.
