Abstract: A photoelectric actuating system including a base, an illuminant, at least an optical receiver, at least an actuating apparatus and an optical mechanism is provided. The illuminant is fixed in the base for emitting a light beam. The optical receiver is also fixed in the base. The actuating apparatus is electrically connected to the optical receiver. The optical mechanism can be disposed at an actuating position in the base for transmitting the light beam from the illuminant to the optical receiver so that the optical receiver can send an actuating signal to actuate the actuating apparatus.
