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.
