An optical transmitter receiver switch incorporating a fiber optic light guide for communicating between electrically isolated circuits. Each switch has a photoemitter and a photosensor in optical communication with each other and with one end of the light guide. The photosensor and photoemitter are enclosed in an opaque housing and communicate with each other and the light guide via a transparent optical cavity. There results an unusually versatile optical isolator which, when in optical communication with a second optical transmitter receiver switch, forms the preferred relay.
