  • Patent number: 6163275
    Abstract: The present invention discloses a system for remotely controlling a switch and a light. In the preferred embodiment, a conventional remote control is used to turn a light to a maximum setting. All received pulses thereafter within a given Null Time will smoothly reduce the electrical load thereby dimming the light. An indicator LED will be provided to demonstrate that the remote signal is reaching the remote switch. If the unit remains in an "on" condition or the Null Time, the next pulse will turn the light fully off. A learning mode is also provided which allows a button on a conventional remote to be pressed for a certain period of time. The switch will thereafter recognize that remote function key as the switch to control the light. The remotely controlled switch has a line interface electronically connected with the power supply. The power supply then electronically connects to an infrared sensor and a processor.
