Review on MICTUNING Backlit LED Light BAR Symbol Push Button - Toyota ON-Off Switch - White, 1.28 x 0.87 inches by Robert Weeks

As other reviewers say, this button works fine until you install it in the 4Runner case. Something is preventing the button from fully engaging, making it an instant-on button. I fixed it by finishing the inside edge of the button. This is not visible after installation. First I tried sanding the edges. That's why you see the white edge on me. But it did not work. Just start dredging the back edge of the knobs and this will give you the freedom to work properly. OR just buy the best air on board button.
