Infra-red controlled switch
Infra-red remote control units for TVs and video recorders usually have a large number of press-keys to select a staggering variety of functions. For simple on/off remote control applications, such as opening a door or controlling a lamp, these transmitters are far too complex. That is why a much smaller transmitter and an associated receiver are described here. The system is suitable for switching loads up to 1,000 W using a simple toggle on/off function.
