I think a set for Robotron Wico 8ways is a good idea.. except.. Id want the button pretty much the same as that Wico Command Control stick.
A Leafswitch button is far faster to activate, but has a nice initial cushion zone before that... to keep from accidentally pressing the button as your finger rests on it. Once at that activation depth, its easy as pie to bounce lightly, causing lightning fast rapidfire... that no Microswitch can even come close to touching.
The Leafs are less fatiguing for rapidfire action.. and while they are designed with a very long travel.. you do not have to bottom out the button to activate them. As a result, there is no Impact into your fingers, from standard buttons that are designed to bottom out. Again, less fatigue, and greater comfort.
And.. they are whisper silent. Even IF you managed to bottom them out.. the spring forces that are at play, as well as the thinner button shaft, are such that its still a lot quieter than a typical button. Happs wide hollow buttons tend to amplify the sounds.
Id probably prefer the button top was more shaped and sized like a Sega Genesis button. While the button would stick up twice as tall as a Sega button... its top would be the same concave finger-cradling shape, so as not to slip off of it.. as well as for better comfort. Convex buttons, especially small diameters.. can end up causing pains from long and or intense sessions. The larger genesis button diameter, about a dime or penny size... would be easier to stay on, and more comfortable. Probably would look a lot less like the Pink Oobsies shown here.
The travel should remain long, with the same tension found on typical leaf buttons.
It would be great if these were case into a hollow translucent shell, with UV reactive colors, to match the Tron Handle sticks/look. Probably the glowing blue top with a translucent frosted milky white button top. And a set of glowing Red, matching the Satans Hollow sticks. Both could use the same white top button... or possibly see how a combo of UV lime green for the blue sticks + UV Orange for the Red.
All the UV colors would be nice... especially for thing like 4 player CPs.
Of course this would also be a great option for Bat Tops as well. Such as to fit onto a Happs Comp.
Im sure a lot would also love a remake of the Original Wico 8way with Rubber Grommet & real leaf switches.
And finally, a set of re-cast Williams fully translucent (not frosted) leaf buttons with the center deflector in tact.
Concave. (with options of UV glow colors that match the said Tron / Button top colors)
An option for installing the centers into a newly made microswitch adapter would be good for a mix of leafs and micros.. but retaining the same beautiful look.
UV reactive artwork and plastic inserts could be cool as well. Could embed them into the CP.
Id also prefer the typical leaf /micro buttons, to have a slightly smaller diameter. Maybe even a mini set - possibly using that same Genesis cast... for use as Start / Coin / Admin buttons.. and or use for smaller bartop & children-builds.
