Massive Arcade Button with LED - 100mm Green ADA_EL Panels and is meant to plugOMG WATCH OUT! This 100mm diameter arcade button with a 16mm deep plastic base is so massive and inviting it may collapse upon itself and form a black hole from which not even light can escape! Until it does, however, it ready for all sorts of pressing and pushing. Science has shown no one can resist pressing its shiny surface and saying "beep!". We've seen these on some games of skill in arcades, they're easy to mount on nearly any kind of enclosure.
