Review on ESUPPORT 15 X Car Boat Rocker Round Dot Toggle LED Switch Blue Red Green Light On/Off 12V 16A by Lloyd Rodriguez

Seems good value at 50 cents (US) for the switch. Five of the switches I received were marked 20A/12VDC. The other fifteen were 16A/12VDC. The 20A switches light up with either straight or reverse polarity, which is a bit odd. The circuit/LED illuminates (closes) when the non-LED portion of the switch is depressed or in the down position. For 16A switches, the LED is polarity sensitive, which is normal. The LED and circuitry are on when the LED portion of the switch is depressed/down. This is the opposite of the 20A switches that were on. You can also light the LED by applying voltage to the middle terminal A. This differs from 20A switches where the LED can only light when the switch is closed.
