Abstract
The present invention teaches a control system wherein fiber optics controls the functioning of one or more types of wiring devices, such as a wall receptacle. With the use of the present invention, a relatively safer system is provided for use in wet, hospital, explosive and other environments, and which is capable of surface mounting. Switch and load supply assemblies are interconnected by fiber optic means for transmitting reflected signals from a movable mirror to a photocell-influenced relay circuit.
