Hi there.

The inventor that I am, I just had a thought for a mechanical keyboard mechanism. So here it is:

In the usual mechanical (Cherry MX, alps etc) switches, you have a spring. Well, instead of a spring, why not use two tiny magnets, with their like poles facing, so that they push away from one another, as a "springy" feeling but with a difference?

Also, as a variaton on this, I had an idea to have one permanent magnet in the stem, opposing an electromagnet (fixed) in the body of the switch, the current to which could be adjusted, therefore adjusting the key resistance level. This idea seems incredibly simple to me, and I am of the opinion that simple is usually best, no?

It would probably require more external power... but who knows?

Thoughts? Has this been done?

Thank you

Yes.

You might want to read up on hall effect switches^^.

Ooh yeah, software-programmable tactile feedback.

Also, when you power on the keyboard, you can have the keys rise slowly into position, preferably accompanied by a hissing sound PSSHHHHHHHFT and a solid THUNK at the top.

Not software-programmable, hardware-programmable! That would be cool. You can plug your keyboard into any PC and always have the same feeling. But I fear that this kind of switch wouldn't really feel nice, as afaik magnets don't follow hooke's law as springs do, so these keys would feel bad. A little like MYs, with the force increasing as you push it down.

Hooker's law: it's hard out there for a pimp.

This is spring-related, and nothing to do with the switches. You're talking about a totally different aspect of the key; the switch, whereas I am tallking about the force required to actuate the switch, being variable by means of magnetic repulsion caused by the like poles (N+N or S+S) of two magnets - one fixed permanent, one electromagnet, with variable current input.

Oh THAT.

Old, but good. It's often the ideas that are considered "old" and thus dismissed, that end up being the best ones of all. Great minds think likewise, it seems.

Could you please stick to your own opinions instead of contradicting yourself within minutes?

Okay.

So, are you interested in my ideas? It seems not, if you're laughing them off. I promise not to sell you one at cost price, once they're released... okay.

I designed the wheel, the bag-less vacuum cleaner and every iteration of space shuttle there is/was.
