I purchased and installed these momentary switches for a project I was working on and they turned out great. They came with a wiring cord and I wired them so that when the power was turned on to the main nitrous switch all the nitrous related momentary switches would light up and be operational, I used the blue button for checking and the white for cleaning. The fact that they are flush mounted is much better than push button switches that go up 3/8" to 1/2". I did too when I came back and ordered more for future use.
