These are the sturdy little stomp switches that you find on guitar effects pedals.
They're DPDT on/on type switches which mount into a 1/2" diameter hole.
You'll need at least 7/8" of depth beneath your mounting surface to accommodate the switch body.
Use these as replacements in some types of effects pedals or, better yet, build your own!
