Wireless Switches: Any Radio Geeks Here?

Recommended Posts

I'm thinking about doing my own wireless steering wheel setup, since none of the off-the-shelf items appeal to me. Does anyone see a reason why I couldn't use one of these cheap RF (433 Mhz) setups to control 4 relays? I wouldn't be using these relays to pass high current - I just want to use them to trigger another relay.

I'm assuming that I could remove the transmitter from the fob and convert the 4 buttons into proper momentary buttons on the wheel with some soldering.

 

My main question is about RF @ 433 Mhz in a car. Could it cause interference with something? It looks like other wireless steering products use RF, so probably not, but I wonder if the frequency is important.

 

Cheers!

Cost you a bit more but cheaper than any other option for the same result

I just purchased one and am in the process of wiring it up.

 

Jeff has the same idea
