Leaf buttons were the original type of buttons used on most of the early video games (carried over from pinball machines).
As well as authenticity, proper leaf buttons offer performance differences / advantages. The long throw is more comfortable (and less damaging to old bodies) and if you learn the flutter technique can be fired faster than a microswitch.
We use the short version ( as used by Williams) which means the maximum thickness they will mount in is 18mm. For thicker panels the backside will need to be rebated.
These are the 'snap' version, meaning they are not held together with a metal clip, they snap together via a barbed collar.
We have sourced new leaf switches with gold contacts. The same geometry and leaf stiffness as Williams (and nearly everyone else) used. Note that Williams switches had a deep block, these switches will need mounting on a 5mm or 6mm platform of some kind (depending on panel thickness).
This is how we mount leaf switches on our control panels. A sliding mounting block allows to adjust the cantilever length and hence stiffness.
Compliant orings allow for fine screw adjustment of the switch gap (no more clumsy bending with needle nosed pliers).
