Review on Waterproof 12V LED Ring Illuminated Push Button Switch With Socket Plug - Quentacy 1NO1NC Silver Stainless Steel Shell, Ideal For 19Mm 3/4 Mounting Hole, Red by Jermaine Munajj

A tiny little piece of paper with the pinout would have been nice but NOOOO. Therefore I did not give it 5 stars. You can figure this out on your own with a test meter. In my case the socket that came with the switch had 5 wires that connected very securely to the switch, and the wire colors mapped as follows: RED is LED+; BLACK is LED-; WHITE is SPDT CONTACT COMMON, BROWN is NORMALLY CLOSED CONTACT, and BLUE is NORMALLY OPEN CONTACT. Note also that the switch provides both tactile and audible "clicks" when pressed, which may or may not be desirable for your application.
