I bought a 315Mhz transmitter/receiver pair of postage stamp size boards from robotshop.com. Ebay has them too.
Here is the schematic:
Here is the board layout, which should be redone in surface mount parts some day. I used drawer junk parts and old VCR parts:

Here is LTspice of the 1s and 3s hold for OFF using pulses from V1 which is imitating the 60Hz converted to 0.7vdc from previous LTspice. See 3 second delayed OFF and instant-ON effect:
