Radio Controlled Switch for Ignition

Recommended Posts


I would suggest that you get yourself one of those cheap remote control cars and take out the guts. In my country, you can get an all direction car for about $4. I’m serious. I’ve already bought like 5 that I’ve dismantled and used one for a room alarm. Just replace the back (or front - used to steer the car) motor with a relay the same voltage as the batteries (or approx). Then use the Remote control to activate the relay using the respective keys to which motor you use. You'll probably achieve 20m in the open.

This will save you big time and big bucks compared to building one yourself.

Hope that helps.

Bye! ;D
