Review on 🚗 eFuncar 3Pin 12V 30A Toggle Switch SPDT ON Off, Waterproof LED Lighted Rocker Switch for Car Truck Boat Marine Auto Motorcycle, Assorted Colors (8Pcs) by Brandon Teitel

Switches work great as switches with LED indicators. They are comfortable to the touch and the LED is visible but not too bright, which I find desirable. I would probably never trust these switches with 30 amps, but I'm not saying they will fail. The good thing is that they are rated for 30 amps so probably won't have a problem with 20 amps. The wiring is a bit odd and counterproductive. If the LED is down then the top pin is the battery, the middle pin is the load and the bottom pin is ground to support the LED. You can't swap the battery and load pins because the middle (load) pin is connected to the bottom (ground) when the switch is off. In other words, you're shorting out the battery when it's off when you flip the battery over and boot. There is no good reason for this. In the off position, the center (load) should float straight. The advantage of this is that the user can wire the switch so that the LED turns on/off or is always on depending on the state of the switch, which would be useful if the switch is being used to control a light and the LED is allowing the user to do so allows find the switch in the dark.
