Abstract:
A photoelectric switch is disclosed. An illustrative embodiment of the photoelectric switch includes at least one light source, a reflective surface provided in light-receiving relationship with respect to the at least one light source, a release button engaging the reflective surface and positional between first and second positions, a photocell provided in light-receiving relationship with respect to the reflective surface when the release button is disposed in the first position, a latch control circuit connected to the photocell and a latch connected to the latch control circuit. The light path incorporates a collimator to restrict operation of the system to the relationship of the light source and the retroreflector.
