Touch switch with dimmable backlighting

1. A touch sensor for controlling intensity of lighting electrically connected thereto, the touch sensor comprising:

a touch sensor interface for detecting a touch of a user;

a power supply connected to the touch sensor for controlling the intensity of the lighting; and

a backlight behind the touch sensor interface, and comprising a plurality of light sources for illuminating an entire surface of the touch sensor interface, the backlight being configured to detect an intensity of power output by the power supply to the lighting, and to control a light intensity of the light sources illuminating the entire surface of the touch sensor interface based on the detected intensity of power output to provide feedback to a user;

a single gangbox, wherein an entirety of the touch sensor interface and a power factor correction (PFC)-correcting power supply are contained in the single gangbox; and

a computer interface configured to enable the user to adjust a maximum voltage output setting and/or a minimum voltage output setting of the power supply, or configured to enable the user to adjust a maximum constant current output setting of the power supply.

2. The touch sensor of claim 1 , wherein the backlight is configured to operate the light sources in a low power nightlight mode when the lighting is turned off.

3. The touch sensor of claim 1 , wherein the touch sensor interface is configured to detect a tap from the user, and wherein the touch sensor is configured to control the power supply to either turn the lighting off, to drive the intensity of the lighting to a preset level, or to maximize the intensity of the lighting.

4. The touch sensor of claim 1 , wherein a first circuitry for operating the touch sensor interface and a second circuitry for operating the backlight are located on a single printed-circuit-board (PCB).

5. The touch sensor of claim 1 , wherein the plurality of light sources comprise differently colored lights.

6. The touch sensor of claim 5 , wherein the computer interface is further configured to enable the user to choose which of the colored lights are used.

7. The touch sensor of claim 1 , wherein the touch sensor interface comprises a capacitive linear touch sensor.

8. The touch sensor of claim 1 , wherein the touch sensor interface is configured to control the power supply based on the detected touch.

9. The touch sensor of claim 1 , wherein the power supply comprises the power factor correction (PFC)-correcting power supply.

10. The touch sensor of claim 1 , further comprising a microprocessor that is configured to measure time to determine a total amount of time of the detected touch.

11. A method of controlling a touch sensor comprising a backlit touch sensor interface for detecting a touch of a user, the method comprising detecting the touch of the user;

determining a location of the touch on the backlit touch sensor interface;

determining an amount of time for which the touch occurs;

determining the touch as a tap when the determined amount of time is less than a reference amount of time;

turning lighting electrically connected to the backlit touch sensor interface from on to off or from off to on when the touch is determined to be the tap;

determining whether the lighting is on or off;

turning on backlighting of the backlit touch sensor interface when it is determined that the lighting is off;

turning on a portion of the backlighting in an area of the backlit touch sensor interface corresponding to the touch when the touch is determined to not be the tap; and

performing a dimming operation of the lighting when the touch is determined to not be the tap,

wherein the backlighting comprises a plurality of light sources for illuminating an entire surface of the backlit touch sensor interface, and is configured to detect an intensity of power output to the lighting, and to control a light intensity of light sources of the backlighting for illuminating the entire surface of the backlit touch sensor interface based on the detected intensity of power output to provide feedback to a user,

wherein the touch sensor comprises a single gangbox, wherein an entirety of the backlit touch sensor interface and a power factor correction (PFC)-correcting power supply are contained in the single gangbox, and

wherein the touch sensor further comprises a computer interface configured to enable the user to adjust a maximum voltage output setting and/or a minimum voltage output setting of the power supply, or configured to enable the user to adjust a maximum constant current output setting of the power supply.
