Abstract

An optical switch having a housing [1], a light source [3] and a light detector [5]. The light source [3] and the light detector [5] are located remote from the housing. The light source [5] is connected to the housing with a first light guide [2], and the light detector [5] is connected to the housing with a second light guide [2]. 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 the light beam.
