ABSTRACT:
An addressable power switch for selectively connecting a device to main power in response to command instructions received over a control bus. The control bus supplies a low voltage power source and the addressable power switch includes an energy storage device and charge circuit for deriving a charge current from the low voltage power source and charging the energy storage device. The addressable power switch also includes a latching relay for connecting the device to main power. The change in state of the latching relay is realized through controlling discharge of the energy storage device, which supplies an energy pulse upon discharge. The switch may be used in connection with addressable lighting systems.
