This is an infra-red (IR) toggle switch which we believe will work with any button on any modern remote control module. Push any button of you remote control unit and the relay in our kit will turn on.

Push any button a few seconds or hours later and the relay will toggle off.

All modern IR remote control devices produce a continuous coded stream of pulses at 37.9 kHz when any button on the module is pressed. These IR pulses are detected and decoded by a receiver (you TV, VCR, etc) and the appropriate function activated. In our kit the coded stream is converted into a single pulse and that single pulse is used to toggle a relay on & off. The coded information is lost. Only the fact that a button was pressed on your remote control unit is detected.

This single pulse is then used to toggle the output of a flip-flop. A high on the /Q output of the flip-flop turns on transistor Q3, which in turn operates the relay and the LED. The LED provides visual indication that the relay is operating.
