Review on 🚗 HOTSYSTEM New 3pc Car Truck Rocker Toggle LED Switch - Blue Light On-off Control: Amplify Your Vehicle's Control Panel with Style by Marco Habersham

3 star product, average quality but at such a great price, half a star added. 3.5 stars are rounded up to 4. They come with no schematic, but the two silver spades are for the power input/output, and the copper pin needs to be connected to ground if you want a little light to come out. when the switch is on. What I probably like best about them is how close they are flush mounted, they don't stick more than 1/8 inch or so to their mounting surface. I don't see anything sticking to them or turning on or off accidentally. To install, simply drill a hole of appropriate size (sorry, forgot to measure, but I think it's in the data), slide it in from the front (self-clamping) and connect the cables. It should be noted that these switches use a narrow blade terminal (10 amp maximum) rather than a standard blade terminal (15-20 amp).
