Review on RF Remote Control Switch EMylo Smart Wireless Relay AC 110-240V 2000W 1 Channel Momentary 433MHz Module With 2 Transmitters by Logan Goozmer

the wiring diagram confused me at first but I finally got it.if you're not using the relay for 120v+, i.e., if you're using it for 6/12/24 volts, only one leg is switched, meaning you connect two wires into one terminal to provide power to the relay and whatever you're powering, and then it switches the other leg. You also have to wire in a little jumper. Here's how to wire it:The far right terminal will have both the positive in and positive out, the terminal to the right of it accepts the negative in, the terminal to the right of that accepts the negative of the device you're powering, and the one to the left of that has a jumper that goes to the second to last terminal from the right.
