Abstract
Abstract An improved load control system for lighting fixtures and the like which allows the wires leading to the control switch, or command transmitter, and the transmitter itself to be extremely thin and thus to be cemented to the outside of a wall avoiding time consuming and costly behind the wall installation. The command transmitter operates at a voltage of less than four volts which is coupled over strip lines to a converter module which increases the voltage to in the order of 24 volts to operate line voltage switching apparatus. The converter and switching apparatus are built into a single unit which may be installed directly in a distribution box.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
136 words
Apparatus to permit an operator within a building to remotely switch an electrical load device installed in the building comprising: a. a low voltage source; b. at least one command transmitter having said low voltage as an input and providing, when operated, one of said low voltage and a portion of said low voltage as an output; c. amplifying means having as an input the output of said command transmitter and providing an amplified output at an intermediate voltage; and d. means to couple the load to a line voltage, said means being responsive to the output of said amplifying means, whereby the portions of the circuit with which an operator has contact will be low voltage, low power circuits and may therefore be constructed using thin components and need not be mounted within the walls.
Claim 2
Dependent Claim
136 words
Apparatus to permit an operator within a building to remotely switch an electrical load device installed in the building comprising: a. a low voltage source; b. at least one command transmitter having said low voltage as an input and providing, when operated, one of said low voltage and a portion of said low voltage as an output; c. amplifying means having as an input the output of said command transmitter and providing an amplified output at an intermediate voltage; and d. means to couple the load to a line voltage, said means being responsive to the output of said amplifying means, whereby the portions of the circuit with which an operator has contact will be low voltage, low power circuits and may therefore be constructed using thin components and need not be mounted within the walls.
