Abstract
The invention provides a low current consumption control switch device and method related thereto. The control switch device includes a switch control component, a microprocessor, a wireless signal receiver for receiving control signal and a DC power supply. The DC power supply draws an AC current from the AC power supply to power the wireless signal receiver, the microprocessor and the switch control component. The switch control component has a control input for receiving control instructions to control current supply from the AC power supply. The microprocessor is operatively connected to the switch control component for providing control instructions to alter its switching state. The control signal comprises a preamble and a message portion. The wireless signal receiver is configured to alternate between at least two current consumption modes and to remain in a higher current consumption mode upon detection of the preamble.
