The volcano buttons are quite a simple device, but without the molds to make new parts, they'll have to be made by hand.
The parts are:
- the microswitch (still made by Cherry)
- the lens cap
- a brace that holds them all together.
And that doesn't take into account the LED assembly. And I didn't count the cone since that *is* being made by several people.
A couple years ago I asked Cherry if they'd consider making the button assembly again. They get at least two calls like mine a week. For $25,000 they'll consider it. That's how much it would cost to get new dies made.
So if you can machine some new dies, go for it!
