Great productMounted and wired just the way they should easy.I bought two packs of these toggle switches. Only 5 out if 12 worked.Awesome!Used them in the past, order them a singles, preferred this collection. The light up switch allows for instant recognition of switch position and power. I use them in my drag car for stuff like the nitrous oxide system, electric cooling fans, fuel pump, etc. I chose the multi colors, so each system for function has a color, versus a label.
