In order to save electricity (and be green), I have set the electric in my room so I can turn everything off using a cheapo wireless switch and extention cords. I have always thought that I could use the remote like a relay to trigger the electric with an extravagant switch (in my case a key switch).
No soldering skills required.
Make sure you are not connecting more to the remote switch than it is rated for.
For instance, I bought a heavy duty (3000 watt) one. Most are only rated for a light or two. Be careful.Here
is a remote like the switch I used (but lower wattage).
