1. A system for controlling electrical power to a load comprising, in combination:
- (a) a dimming system to control power to said load in accordance with a signal provided by a control means, which includes an actuator positionable for determining the value of said control signal,(b) override means to permit power to said load when said actuator is positioned for power to said load to be off, and(c) a first switch means, which(i) if power to said load is on, turns said power off; and
(ii) if power to said load is off, turns said power on to a value determined either by said actuator position or by said override means.

Abstract
A multiple location system is provided for controlling application of alternating-current power to a load. The system employs a dimming system in combination with one or more switches. In one embodiment, the system includes an override, so that a switch can provide power to the load even after the dimmer has turned the power off. In another embodiment, the dimming system includes an actuator, and the value of power to the load is determined substantially immediately upon setting of the actuator.

10. A system for controlling electrical power to a load comprising, in combination:
-
(a) a dimming system to control power to said load in accordance with a signal provided by a control means, which includes an actuator positionable for determining the value of said control signal, (b) means for automatically applying to said load, substantially instantaneously upon positioning of said actuator, a power value determined by said control signal, and (c) a first switch means, which (i) if power to said load is on, turns said power off; and (ii) if power to said load is off, turns said power on to a value determined by said actuator position. - View Dependent Claims (11, 12, 13, 14, 15)
