Abstract
Systems and methods are provided for controlling light in a 3-way light circuit, where at least one of the switches in a 3-way light circuit includes an occupancy sensor and the on/off state of the load in the 3-way circuit is determined based on the voltage output of circuits configured to provide power to the 3-way light circuit.
Claims23
A switch comprising:
- a controller for controlling output to a load, the controller comprising a first power input and a second power input;
- a first terminal for connecting to a common line;
- a second terminal for connecting to ground;
- a first traveler terminal;
- a second traveler terminal;
- a first power circuit configured to receiving a first input from the first traveler terminal, and output a first power derived from the first traveler terminal to the controller via the first power input;
- and
- a second power circuit configured to receiving a second input from the second traveler terminal, and output a second power derived from the second traveler terminal to the controller via the second power input.
5 more elements
A circuit comprising:
- a first 3-way switch;
- and
- a second 3-way switch;
- wherein the first 3-way switch and the second 3-way switch are connected in a 3-way circuit configuration, and at least one of the first and second 3-way switches comprises:
- a controller for controlling output to a load, the controller comprising a first power input and a second power input;
- a first terminal for connecting to a common line;
- a second terminal for connecting to ground;
- a first traveler terminal;
- a second traveler terminal;
- a first power circuit configured to receiving a first input from the first traveler terminal, and output a first power derived from the first traveler terminal to the controller via the first power input;
- and
- a second power circuit configured to receiving a second input from the second traveler terminal, and output a second power derived from the second traveler terminal to the controller via the second power input.
9 more elements
A method for providing on/off control in a 3-way circuit, comprising:
- configuring at least one 3-way switch comprising a first terminal for connecting to a common line, a second terminal for connecting to ground, a first traveler terminal and a second traveler terminal;
- receiving a first input from the first traveler terminal, and outputting first power derived from the first traveler terminal to a controller of the at least one 3-way switch via the first power input, the controller controlling output to a load;
- and
- receiving a second input from the second traveler terminal, and outputting second power derived from the second traveler terminal to the controller via the second power input.
