Abrégé

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 guides have distal ends coupled to the activation, and a part of the activator housing or movable member is a glowable diffuse reflector. The switch moveable member moves in a path in the switch body between an optical path present state and an optical path absent state.

Abrégé

An optical switch having a housing, and two optical fibers, that can be connected to a light source and a light detector. The optical switch includes a moveable member that moves from a first position to a second position. In the first position, an optical path is present through the two fibers guide using a reflection or emission of light from the glowable member. In the second position, there is no optical path present through the switch.
