A photoelectric induction pedal signal collector. Two circuit boards (9) are mounted on a plastic plate (6) of a bottom box (5). A pair of transmitting light emitting diode and receiving light emitting diode (10, 11) is mounted on the circuit board (9). A rotation shaft sleeve (12) is welded at two sides of the bottom box (5). A rear shaft (13) passes through the rotation shaft sleeve (12). Swinging ring screws (15) are sleeved at two sides of the rear shaft (13). A front shaft (19) connects left and right shaft sleeves (16, 18) and a rotation shaft screw (17). Two nuts are mounted on the rotation shaft screw (17). A spring shaft sleeve (8) is arranged in the middle of the bottom box (5). A spring (7) is arranged on the spring shaft sleeve (8). Raised portions at left and right sides of a hardware bracket (2) on a top box (1) are staggered. A plurality of ribs is arranged on the surface of the top box (1). Circuits in the two circuit boards (9) are completed in the following wiring manner: two capacitors, a current-limiting resistor, and two transmitting light emitting diodes are connected in parallel, each of the two transmitting light emitting diodes is connected to a resistor in series, and each wiring pole (2, 4) in the two circuit boards is connected to a receiving light emitting diode corresponding to the transmitting light emitting diode. Through the photoelectric induction pedal signal collector, the problems of false operation caused by a pedal control signal, contact aging, an electrical failure, and an electric arc generated by a contact can be solved, and the service life and safety performance can also be improved.
