Abstract
An apparatus for isolating driver circuits from silicon-controlled rectifier (SCR) circuits in an electric switch. The driver circuits are located on a driver-board, which includes an infrared (IR) emitter. The SCR circuits are located on a SCR switch-board, which includes an IR receiver. An insulating body is positioned between the driver-board and the switch-board. The insulating body encloses a light-pipe to optically link the infrared emitter to the infrared detector. Control signals can be communicated from the driver circuits to the SCR circuits via the IR emitter, the light-pipe, and the IR receiver.
