I have a serious question about Topre switches, that maybe someone here can answer. I know the mechanism for actuation is capacitive, but what causes the capacitance? The metal spring coming in close proximity to the pad?


Without the spring, the switch would not work

edit: this forum is far too pedantic - when i say "work" i mean the capacitive "jump" would never happen, and the key would never "fire". It will still move up and down like it should though

AFAIK it's due to the fact that a conical spring in the shape as those used by Topres increases in capacitance as it gets depressed and the spring coils move closer to each other.

The circuit detects when the capacitance reaches a certain threshold and then closes.

Wow... just caught up. People in here are getting way too uppity. Some like Topre (like me), some don't. Whatever.

For me, I love the combination of high quality rubber dome over a steel plate/PCB, which most keyboards that we label "rubber dome" don't have. Those are usually rubber dome over plastic membranes. Much more of a mushy feel. Some prefer that, most don't.

And there are some RD over membrane boards that feel crisp and buttery smooth. Probably my favorite was this bad boy right here:



That had a firm bottom-out feel due to the caps hitting the plastic base. Great board there, lasted me many years before I found mechanicals.

People are so touchy... it's obvious that iri isn't that big a fan of the bottom out feel of Topres, and that's fine. He doesn't have to. Nobody has to. I enjoy my Topre switch boards, and I don't have to tell myself that I do in order to "justify" it. I spent a lot on them, and I don't regret the purchase. There are those who might. And that's ok too. At the end of the day, we're all just fans of fine typing devices here, right?

By immediately assuming I was referring to you ;) (which I wasn't, actually).

Topres are rubber domes. They're just exceptionally good ones (IMO).

Dome, sorry they're identical with the exception of actuation distance...

But they aren't identical. That exception is the major difference, not to mention the quality and thickness/durability of the rubber.

Topre: Cup


Rubber DOME:

You're having a disagreement with tp and trying to use words and pictures to show him that he's wrong.  You'd have better luck convincing the bro bot in your avatar that it was a new girldc Gundam cap...

Also, a related question, is it possible, while typing normally, to actuate the switch without bottoming out?
i asked the same question here once, and got a reply "no, that's not possible, but that's okay, as bottoming out on topre is nice".

Yes, actually. I was more making a generic comparison between standard rubber domes and the RealForce breed of Topre. I still love RF's more than everything except the HHKB. Apologies.

i can't wait to the moment when people start using the word MEMBRANE to distinguish conventional rubber dome keyboards from capacitive rubber dome topre.

uh actually iMav came up with the initialism RDOMS probably years before you were aware of topre... rubber dome over membrane switch.

the rest of you are cracking me up with how defensive you get about rubber... yes, topre is rubber dome. it feels nice. use it if you like it.  ¯\_(ツ)_/¯

This is degenerating into the newbie thread like:

"Just Tell Me What is the Best Keyboard So I Can Buy It"

My wife loves Apple's flat scissor keys with minimal travel, so "there is just no accounting for taste" right?

Give me a heavily-modded Model F, but that's just me.
