Abstract
A goods delivery switch includes a bracket, a rotating member, a delivery member, a signal generator, a signal receiver, a blocking member, and a control unit. The rotating member includes a second blocking curved plane and a cutting plane. The delivery member is operable to rotating the rotating member. The blocking member includes a first curved plane and defines a through hole. The blocking member is slidable relative to the blocking member between a first position, where the rotating member is rotated, the first curved plane abuts the second curved plane, and the signal receiver receives an optical signal from the signal generator through the through hole, and a second position, where the first curved plane abuts the cutting plane, the optical signal is blocked by the blocking member, and the control unit controls the delivery member to stop operating, relative to the bracket.
