The utility model is suitable for the field of optical devices and provides a motor photo-switch integrated with a wave combining function. The motor photo-switch comprises a stepping motor, a mechanical arm and a graduated plate. A plurality of through holes are distributed on the outer ring of the graduated plate at equal angular intervals. A transmission collimator is fixed at the far end of the mechanical arm. A wave combiner reflecting end is fixed in each through hole of the graduated plate. The transmission collimator comprises a first optical fiber. Each wave combiner reflecting end comprises a second optical fiber, a third optical fiber and a wave combining film arranged at the front end. Under the driving force of the stepping motor and the mechanical arm, the transmission collimator is correspondingly coupled with all the wave combiner reflecting ends in sequence. The motor photo-switch provided by the utility model can be used for detecting more ONU (Optical Network Unit) channels and has the adva
