This is a schematic circuit diagram of a remote controlled switch for home appliances.

Remote switch circuit diagram. This circuit works with any infrared remote using for tv dvd usb player etc. This circuit is built using ic cd 4017. Wireless bells in stores but making it at home will save you a lot of money and also teach you the working concept of these bells.

List of all the electrical components used in this circuit given below. So we have connected a 1uf capacitor across the output of the tsop so that this 38khz pulse train is counted as one clock pulse to the ic 4017. Ir infrared remote controlled switch circuit diagram for light fan.

Remote control for appliances. Electronic password door. This is the very simple circuit diagram of the ir remote control switch.

Remote controlled switch circuit diagram notes. In this circuit there are two relays are used the first relay is used for giving input signal to ic according to changing pulse from the sensor the second relay is used for connecting load ie fan light etc. For each input pulse the output of cd4027 goes high and low alternately.

The circuit presented serves as a remote control switch. A 12 volt relay is used in this circuit which acts as a switch. Before wiring the circuit make sure that the carrier frequency of the tv remote you have is 38 khz for that wire the sensor part only point your remote to the tsop1738 and press any switch if out put of tsop1738 goes low then ok your remote is of 38khz type nothing to worry almost all tv remote are of this type.

The working range is upto 20 meters. This is a good solution for a unique and so interesting idea to wireless switching system to control the home appliance. Remote switch circuits.
