摘要： An optical switch having a housing, a light source and a light detector. The light source and light detector are located remote from the housing, The light source is connected to the housing with a first light guide, and the light detector is connected to the housing with a second light guide. The first and second light guide cables have distal ends positioned through the housing and are optically aligned but separated by a gap. The switch includes a device to interrupt a light beam that is usually adapted to removably occupy the gap. The switch may be embodied in a float.
