Review on 🔌 Wireless RF Relay Remote Control Switch, QIACHIP 12V 1CH 433Mhz Momentary Light Transmitter with Receiver (1 Relay) by Todd Hauff

You can use this to remote control anything on a basic single pole double throw relay. I used it to trick my jeeps horn so I could pass inspection without having to replace a very pricy part.The best features are that it's compact, it has, NO and NC, it runs on an easy 12v, and it also has constant pressure activation instead of pulsed. Good little device for any little project you may have. It also breaks apart really easily so you can integrate the circuitry. Also the remotes circuit board around the button is big enough to solder your own remote switch to without having to remove the original button (witch is what I did)
