ABSTRACT:
A light transmission load control system including a light responsive load controller for controlling a load setable in two states in response to optical impulses generated by an optical impulse generator. The optical impulse generator includes a light-emitting device for emitting optical impulses in response to electrical impulses produced by an electrical impulse generator. In its simplest form, the electrical impulse generator has a single moving part for controlling and indicating the state in which the load is set.
