Review on 🔄 APIELE Momentary Button Mounting Self Reset: Streamline Your Control System with Easy Reset Capabilities by Tyrone Lyons

Great switch, nice LED light. As some have noted, the connection instructions leave a lot to be desired. I wired the switch so that the LED only lights up when the button is pressed. Here's how it works: Green wire from the switch to the power supply, blue wire from the switch to the device you're powering. If the device (in my case the electric fuel pump used for priming) is grounded, the switch will now turn the device on without any additional wiring. The LED has its own circuitry that is separate from the device circuitry. To have the LED light up when a button is pressed, connect the red wire from the switch to the blue wire connected to the device in the same butt connector (or whatever connector you use). Then the black wire from the switch on the vehicle frame must be grounded. I cut the yellow wire and seal the end with tape to prevent unwanted contact. This simple description would have saved me half an hour and a blown fuse trying different wiring combinations.
