It's the end of the world, and you need a button to press. This is it. A 100mm diameter (outside diameter) dome illuminated push button comes with an LED, securing nut and a pre-installed long life horizontal microswitch. Button can also be adjusted to a low profile button by removing the middle ring.

These are economy grade big dome push buttons, these guys may rattle, have a weaker spring, and may not have as bright of an LED as the standard big dome push buttons.
Weak points aside, these buttons still work great and will get the job done.
