What determines the actuation point of a switch?

[Gower]

I've noticed that theres brands like Kaihl's "Speed" series of switches that show off low actuation points at almost 1.1 mm. I know this is mostly irrelevant for gaming and its a preference, but seeing how it varies on different switches, what determines it? Is it the height or placement of the switch leaf? Or is it related to the housing? There doesnt seem to be much info on this, but I wonder if you could create a frankenswitch that has most of the attributes of a higher end switch with the actuation point of a "speed" series switch.

Thanks for reading!

It should be the actuation point on the stem itself. Moving the bump up higher makes it actuate faster. There isn't really a way to replicate this without using the stems from speed switches.

That's actually backwards but the right idea, the lower down the stem the bump the sooner it hits the contacts.

And you can actually duplicate it with blues and greens, that was the purpose of Jailhouse Blues. Don't do that though, now that we have switches already made this way it's become moot.

Gower, by watching them in action it might be easier to understand what's going on inside the switch.

QMX clips with slightly more padding on the upstroke portion (so the under part of the clip) will have the keys at rest closer to actuation...but basically you give up some travel to achieve that. 

I haven't tried it but have thought about it..
