PROBLEM TO BE SOLVED: To provide remote control power units which avoid a possibility of unwanted interference caused by a relatively limited number of codes in communication between a remote control and a switch enabled by setting the remote control and the switch to the same code.SOLUTION: A remote controlled switch system has a hand-held remote control for turning power to a controllable switch on and off by radio waves. Each remote control unit contains at least one unique identifying code and can be linked to one or more separate controllable switches. The number of controllable switches that can be controlled by a single hand-held remote control is essentially limitless. |
