Review on MKING Marine Waterproof Rocker Switch - 12V 20A Blue LED - 3-Pin Boat/Cars/RVs/Yachts Switch by Homer Reed

I have purchased a DCFlat 3 pin 12V 20A Waterproof Blue LED Illuminated On/Off Rocker Switch (5 Blue LEDs) sold on 26th February by Dcflat-direct, and have just started the installation . My project was to add extra lighting to the front and back of my F250 pickup truck. I wanted to replace the switches that came with the Mictuning harnesses with these switches. It was so easy to pull the wires out of the harness switches and attach them to the new switches. I really like the new switches so far. They have a solid sound and feel when turning on and off. The LEDs only light up when the switches are in the on position. Don't worry about battery drain. Time will tell if the LEDs are too bright at night. If so, I'll darken them with masking tape or a black marker. As others have said the switches do not come with a schematic. Mine are laid out like this: two contacts are close together on the bottom of the switch and one is on the top of the switch. The top pin is the bottom. The lower contacts are for the power supply. The top pin connects to your ground source. The middle pin connects to the battery/12v power supply, the bottom pin to your accessory, in my case an extra lightbulb. The purchase went smoothly. Delivered as promised and the price ($13) was very fair. I have paid so much for a switch in the past. Now I have three left for other projects!
