Patent ID: 7598631

Claim:
An addressable power switch for connecting a device to a main power source, the power switch being connected to a control bus, wherein the control bus includes a low power source, comprising: an energy regulation stage for receiving the control bus input and outputting a regulated DC voltage derived from said low power source; a controller having an input port connected to said control bus input and an output port for supplying a control signal; an energy storage device; a charge circuit connected to the energy regulation stage for charging the energy storage device using said regulated DC voltage; and a switching stage for selectively connecting said device to said main power source in response to said control signal, said switching stage including a discharge switch and a power relay, wherein said discharge switch is responsive to said control signal for connecting said energy storage device to said power relay thereby at least partly discharging said energy storage device through said power relay and actuating said power relay, wherein said power relay connects said main power to said device.
