Review on 🔋 ESUPPORT Black 19mm 12V 5A Power Symbol Angel Eye Halo Car Green LED Light Metal Push Button Toggle Switch Socket Plug Wire Waterproof for Improved SEO by John Hall

The switch has a good positive locking mechanism. The plug is of good quality and fits nicely on the back of the switch thanks to the built in plastic latch. A circuit diagram is not included, but normally open, normally closed and common connections are marked on the back of the switch. It is also correct to assume that red is positive and black is negative to power the lightbulb in the switch. The delivery time was quicker than expected and it was well protected in bubble wrap. The perfect switch for the circuit on/off function I want on my road bike.
