Abstract
A module for interconnecting an AC power line to a load such as a lamp, which includes a first switch. The module detects the state of the first switch and then provides power to the load when the switch is closed. Sequentially opening and closing the first switch can be used as a command to dim the lamp. The module may also include a transceiver which communicates the state of the switch to the other modules thereby allowing a plurality of devices to be controlled by the first switch.
