In the reflective photoelectric switch, the light emitting polarizing filter and the light receiving polarizing filter are attached to a transparent base plate having an opaque band so as to be adjacent to each other, and adjacent portions of both the polarizing filters are located in the opaque band. A retroreflective photoelectric switch featuring:
