Review on 🔴 Veanic 5pcs 12V 30 Amp Red LED Rocker Switch for Car Truck RV Motorcycle Boat Marine Control - Waterproof Toggle Plug (Toggle Switch A) by Eric Basler

As others have said, the quality is lame. 3 out of 5 switches are shorted to ground in the off position. All 5 worked as a simple 2 pin switch, but adding a ground to turn on LED 3 caused a short in the off position. I'm glad I always secured all power lines otherwise I could have had a bigger problem. I'm not sure how "waterproof" they actually are, the switch body is fully exposed to water so if it gets wet it may short out or turn on in the off position. They appear to be sealed going into the base where the pins are, so water is unlikely to get into the box they are installed in.
