RTA-80 Teletype Keyboard

It's a new week! And I'm still here!

Remember, that force curve I was taunting some months back? photos-f62/a-switch-has-been-d-is-c-o-v-r-d-t13496.html
Figured it's time to unveil this piece of Soviet Goodness.

What's really interesting about this switch, is that I'm not aware of anything this is a clone of. I daresay there's real design engineering here

While, I'll leave it to the gallery to determine whether this is actually nice to type on, it exhibits a force curve that we don't usually see in switches, a sheer tactile point. What's even more interesting, is that this is achieved entirely with magnets (there are two magnets in each switch, one for tactility and one for the reed switch).

But enough out of me, here's some force curve goodness.

One of my guesses had it using a magnet for tactility! I feel validated.

A tactile magnet and an INVERSE tactile bump. Also, integral diode and magnetic reed with Hall effect pinout. Whatever will they come up with next?! Oo

Seriously this has to be one of the coolest switch designs I've ever seen.

Echo everything Chryos said, there's a lot going on inside that switch. One of the coolest designs I've ever seen. After flipping through the full album on flickr, I've come to the conclusion that the reed/diode assembly is strangely beautiful.

Shouldn't that be PTA-80?

It's cyrillic, so P->R.

I'll have to make my own reed switch based keyboard, as far as I can tell. It's too cool technology not to.

But how... that's another question.

webwit I confirm it's RTA

This is the device:

Description, in russian: http://www.nicostrans.ru/impudent/jelek ... rta-80.php

And "R" is not for "Russian", it's for "Рулонный" - it printed on a roll of paper.
There was LTA-8 - Ленточный - which used paper tape, victorian-era-style.
Haven't seen any of those myself tho.

Post office I had privilege to work one summer jumped from T-100 (look at that keyboard dust protector!) - which is actually a licensed Siemens copy produced in Brno, Czechoslovakia.

straight to F-2000

Which was made in another non-existing country called DDR. This one was fun, actually. Memory buffer (pretty large one), printing to punch tape or regular paper.. Keyboard wasn't too bad either.

No, this is not PTA-80.

This is the P-115A.

Здравствуйте.
Подключил свой РТА-80Л к интернету. Новости печатает неплохо, к примеру ВВС.
