A hands-free faucet comprises a proximity sensor, a logical control, a handle including a first touch control, a second touch control, and a mode indicator. The logical control has a manual mode (wherein the proximity sensor is inactive, and water flow is toggled on and off by positioning the handle) and a hands-free mode (wherein water flow is toggled on and off in response to the proximity sensor). The first touch control puts the faucet in the hands-free mode when touched by a user. The second touch control toggles the logical control between the hands-free mode and the manual mode when touched by a user. The mode indicator indicates which mode the faucet is presently in. The water flow has a temperature and a flow rate that are determined by the position of the handle.

What is claimed is: 1. A hands-free faucet comprising: a handle comprising at least one touch control; a proximity sensor having an active state and an inactive state; a logical control, having: a manual mode, wherein the proximity sensor is inactive, and wherein positioning the handle toggles wate
What is claimed is: 1. A hands-free faucet comprising: a handle comprising at least one touch control; a proximity sensor having an active state and an inactive state; a logical control, having: a manual mode, wherein the proximity sensor is inactive, and wherein positioning the handle toggles water flow on and off; a hands-free mode, wherein water flow is toggled on and off in response to changes in the state of the proximity sensor; and a mode-controller that toggles the faucet between the hands-free mode and the manual mode; wherein said at least one touch control controls activation of water flow through the faucet in response to contact with the handle that is insufficient to change a position of the handle. 2. The hands-free faucet of claim 1, wherein said at least one touch control activates water flow when the handle is touched. 3. The hands-free faucet of claim 1, wherein said at least one touch control deactivates water flow when the handle is released. 4. The hands-free faucet of claim 3, wherein said at least one touch control deactivates water flow when the handle is released following a time delay. 5. The hands-free faucet of claim 2, wherein the water flow has a temperature and a flow rate that are determined by the position of the handle. 6. The hands-free faucet of claim 1, wherein the handle includes the mode-controller, and touching the handle activates the hands-free mode. 7. The hands-free faucet of claim 6, further comprising a second mode-controller that toggles the faucet between the hands-free mode and the manual mode. 8. The hands-free faucet of claim 1, wherein the faucet is configured as a kitchen-type faucet. 9. The hands-free faucet of claim 1, wherein contacting said at least one touch control toggles water flow through the faucet. 10. The hands-free faucet of claim 1 wherein said handle further comprising a second touch control. 11. The hands-free faucet of claim 10 wherein said second touch control is constructed and arranged to toggle the faucet between the hands-free mode and the manual mode when touched by a user. 12. The hands-free faucet of claim 11 which further includes a mode indicator that indicates which of the manual mode and the hands-free mode the faucet is presently in. 13. The hands-free faucet of claim 1 which further includes a mode indicator that indicates which of the manual mode and the hands-free mode the faucet is presently in. 14. The hands-free faucet of claim 1 which further includes a flow detector for detecting whether or not water is flowing through the faucet. 15. A faucet comprising: a manual valve; a pull-down spout; a proximity sensor having a detection zone, the proximity sensor generating a proximity signal when the proximity sensor senses the presence of an object within the detection zone; and an electrically operable valve in series with the manual valve, the electrically operable valve toggling based on the proximity signal. 16. The faucet of claim 15, further comprising: a touch control that generates a touch signal; and wherein the electrically operable valve toggles based on the touch signal. 17. The faucet of claim 15, further comprising: a touch control, comprising: a touch sensor; and a logical control that generates a touch signal when the touch sensor is touched and released within a period of time less than a predetermined threshold, but which does not generate the touch signal when the touch sensor is touched for a period longer than the predetermined threshold; and wherein the electrically operable valve toggles based on the touch signal. 18. The faucet of claim 17, further comprising: a proximity sensor having a detection zone, the proximity sensor generating a proximity signal when the proximity sensor senses the presence of an object within the detection zone; and wherein the electrically operable valve toggles based on the proximity signal.
