First of all you have to mention how far you need to send the remote signal.

about 1 meter

Here is a simple R/C transmitter and receiver on 27MHz. The transmitter crystal could be replaced with any other crystal around that frequency range. The RX relay could be replaced with a buzzer, etc.

I was thinking to this, but I said to myself that 1m is too far for me to get the feeling. I would like << 1mm.
