Abstract

A switch for controlling delivery of electrical current to a light. The switch may include a frame, a controller connected to the frame, and a toggle connected to the frame to pivot through a range of motion having a first extreme and a second extreme, opposite the first extreme. The toggle may toggle between a first position proximate the first extreme and a second position proximate the second extreme. The switch may further include a sensor connected to the frame and positioned to detect the toggle in the second position, and a tactile switch connected to the frame and positioned to be actuated by the toggle pivoting past the first position toward the first extreme. The switch may also include a controller connected to the sensor and tactile switch to receive inputs therefrom and to execute logic to control the delivery in accordance with the inputs.

Claims (24)

1. A switch for controlling delivery of electrical current to a light, the switch comprising:

a frame;

a controller connected to the frame;

a toggle connected to the frame to pivot through a range of motion having a first extreme and a second extreme, opposite the first extreme, and to toggle between a first position proximate the first extreme and a second position proximate the second extreme;

a sensor connected to the frame and positioned to detect the toggle in the second position;

a tactile switch connected to the frame and positioned to be actuated by the toggle pivoting past the first position toward the first extreme; and

the controller connected to the sensor and tactile switch to receive inputs therefrom and to execute logic to control the delivery in accordance with the inputs.

2. The switch of claim 1 , wherein the controller comprises a processor programmed to execute a POWER ON function whenever the sensor senses that the toggle has toggled out of the second position and a POWER OFF function whenever the sensor senses that the toggle has toggled into the second position.

3. The switch of claim 2 , wherein the processor is further programmed to execute a DIM function upon activation of the tactile switch, the DIM function progressing the delivery through a repeating pattern comprising cycling between delivery of a maximum electrical current and delivery of a minimum electrical current.

4. The switch of claim 3 , wherein the processor is further programmed to exit the DIM function upon deactivation of the tactile switch.

5. The switch of claim 4 , wherein the processor is further programmed to maintain the delivery at a first value corresponding to a first state existing immediately prior to the controller exiting the last, previous, DIM function.

6. The switch of claim 5 , wherein the POWER ON function comprises returning the delivery to a second value corresponding to a second state existing immediately prior to the controller executing the last, previous, POWER OFF function.

7. The switch of claim 6 , wherein the sensor is a sensor that detects the presence of the toggle in the second position without contacting the toggle.

8. The switch of claim 7 , wherein the tactile switch is a push-to-make switch.

9. The switch of claim 8 , further comprising an air gap switch connected to the frame and positioned to be actuated by the toggle pivoting past the second position toward the second extreme.

10. The switch of claim 9 , wherein the air gap switch is a push-to-break switch.

11. The switch of claim 1 , wherein the controller comprises a processor programmed to execute a DIM function upon activation of the tactile switch, the DIM function progressing the distribution through a repeating, cyclical pattern comprising a maximum distribution of electrical current and a minimum distribution of electrical current.

12. The switch of claim 11 , wherein the processor is further programmed to exit the DIM function upon deactivation of the tactile switch.

13. The switch of claim 12 , wherein the processor is further programmed to maintain the distribution at a first value corresponding to a first state existing immediately prior to the controller exiting the last, previous, DIM function.

14. The switch of claim 13 , wherein the POWER ON function comprises returning the delivery to a second value corresponding to a second state existing immediately prior to the controller executing the last, previous, POWER OFF function.

15. The switch of claim 1 , wherein the sensor is a sensor that detects the presence of the toggle in the second position without contacting the toggle.

16. The switch of claim 1 , wherein the tactile switch is a push-to-make switch.

17. The switch of claim 1 , further comprising an air gap switch connected to the frame and positioned to be actuated by the toggle pivoting past the second position toward the second extreme.

18. The switch of claim 17 , wherein the air gap switch is a push-to-break switch.
