Photoelectric dumping switch

The invention belongs to electronic components, and particularly relates to a photoelectric type dumping switch which comprises a shell with an inner cavity, a ball bin assembly capable of being installed horizontally and vertically is arranged in the inner cavity of the shell, and the ball bin assembly comprises a bin body, a bin cover, a ball, a photoelectric transmitting tube and a photoelectric receiving tube. And a bottom cover for ultrasonic packaging is arranged at the bottom of the shell. A ball bin assembly with a ball is arranged, a photoelectric transmitting tube is arranged at the bottom of the ball bin assembly, a photoelectric receiving tube is arranged at the top of the ball bin assembly, and a transmitting end cylinder of the photoelectric transmitting tube and a receiving end cylinder of the photoelectric receiving tube directly face the center of the ball, the center of a bin body and the center of a bin cover. Due to blocking of the ball, the photoelectric receiving tube cannot receive light rays emitted by the photoelectric transmitting tube; when the toppling switch topples, the ball deviates from the round through hole in the bottom of the bin body and does not block light emitted by the photoelectric transmitting tube any more, so that the light emitted by the photoelectric transmitting tube penetrates through the round through hole of the ball bin assembly and is received by the photoelectric receiving tube, and the photoelectric receiving tube generates corresponding reaction to prompt that the toppling state is at the moment. Ultrasonic welding packaging is used, manufacturing is easy, packaging is convenient, and the structure is simple.
