Abstract:
1. A rotary switch for controlling a light string, said rotary switch comprising: an input board for receiving power, said input board conditioning said power to provide output DC power at a pair of output power leads; an output board connected to a light string at a pair of color signal leads; a rotary board having a first side and a second side and disposed between said input board and said output board, said first side of said rotary board facing said input board and having a plurality of concentric annular conductive rings, said concentric annular conductive rings making electrical contact with a pair flexible electrical connectors coupled to said input board and said pair of output power leads, said second side of said rotary board facing said output board and having a plurality of custom electrical connection patterns on said bottom side, said rotary board having electrical conductors extending through the rotary board so as to electrically connect said plurality of concentric annular conductive rings to said plurality of custom electrical connection patterns, said plurality of custom electrical connection patterns making electrical contact with a pair flexible electrical connectors coupled to said output board and said pair of color signal leads; and said rotary switch providing a variable DC power pattern to said light string according to electrical connections made with said plurality of custom electrical connection patterns.
