Abstract
A fiber optic relay for an individual light guide according to the present invention includes a first light guide from a remote source of illumination, which is coupled to second light guide in series by a relay having a light shut-off means including an electro-magnetic solenoid. In a preferred embodiment the light is fully off when the solenoid is de-energized and has the solenoid plunger disposed between the first and second light guides, blocking light transmission from the first light guide to the second light guide. When the solenoid is energized from a remote source of electrical power the solenoid plunger is withdrawn from between the first and second light guides, allowing light from the first light guide to pass into the second light guide with low attenuation and high efficiency.
