Here is a versatile remote controlled  switch that can ON or OFF any appliance connected to it using a TV remote.

IR
remote sensor IC TSOP 1738 is used for receiving the signal. Normally
when no signal is falling on IC3 the output of it will be high. This
makes Q1 OFF.When a signal of 38 KHz from the TV remote falls on the
IC3 its output goes low.This makes Q1 conduct and a negative pulse is
obtained at pin 2 of IC 1 NE 555. Due to this IC1 wired as a monostable
multivibrator produces a 4 Sec long high signal at its out put.This
high out put is the clock for IC 2 which is wired as a Flipflop and of ,
its two outputs pin 3
goes low and pin 2 goes high. The high output
at pin 2 is amplified to drive the relay. For the next signal the
outputs of IC2 toggles state.  Result, we get a relay toggling on each
press on the remote. Any appliance connected to this circuit can be
switched ON or OFF.

*
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.

*
You can use any switch  of the remote because for any switch the code
only changes, the carrier frequency remains same.We need this carrier
frequency only.

* Assemble the circuit on a good quality PCB or common board.

* The appliance can be connected through NO or NC and C contacts of the relay .
* Use a regulated 6V power supply for the circuit.
