Title: Cherry swap... only some are clicking. :|
Post by: didjamatic on Sat, 10 April 2010, 20:15:47

I pulled a 1980's laptop apart that had cherry blues in it, swapped the tops/stems/springs over to a G80-1800 that had blacks previously... now some keys click loud, some sort of click and some sound almost like a linear switch with hardly any click at all.  Is there a wrong way to assemble a cherry blue?  Do you have to do anything to the little white plastic thing that goes on the blue stem?  I definitely don't have them in backwards.  I'm seriously going to be pissed if I have to pull all of these things apart again.

Has anyone done this?

Looks like about 25% are not clicking, I'll map them out and pull those apart.  My fingers aren't happy about this.

On the upside, I love these blues on the PCB G80-1800 and double shot caps.

Do the non-clicking switches work?
I transplanted stems and springs from a blue G80-3000 into my G80-2100 and everything works fine. The only way to affect the clickiness I found when messing with other broken boards is bending the contacts. But then, I have a pretty bad eyesight and could barely see what I was doing and still got it right on my 2100. I kinda doubt you're so much blinder and clumsier than me that you managed to bend the contacts of 25% of your switches.

Either the OP made a nasty typo, or no one is noticing the very obvious problem here...

Saw that, but I do trust he didn't try to implant MX tops onto MY bottoms. ;)

This is why I was thinking it's a typo, surely if you tried that with a G81, the OP wouldn't have got as far as he did...

Apparently he has one of Cherry's "exceptions that prove the numbering rule" boards:

Nope, I meant G81, I have a G81-1800 right here with double shot keys and MX switches in it.  :)

Looks like they pulled an ALPS. Only worse.

Well, Alps was relatively consistent. It was moreso when people tried to copy Alps' switches that the **** started to hit the fan.

Wait.  Is this a g81-1800 with article number g80-1800 with Mx blacks originally?

I have done full switch swaps before with boards like 3 times at least.  I have no idea why yours don't click sometimes?  If you use the new spring, new stem, old cover it should click fine.  If you have tried to jam in the stem backwards before sometimes it can bend the contacts of the MX switch.  But i am not clear why some of your's aren't clicking, you better open them up again and re-examine what is going on..

It's a "Made in West Germany" G80-1800 HUA with double shots and MX blacks.  
Here's a photo of the other board I got with it at the same time.  It has MY switches, same exact model number except for G80 vs G81, both doubleshots.

I swapped the full tops/stems/springs over from a Cherry Blue switch laptop, the tops looked the same to me.  All keys register properly, but many don't click.  I'll have to pull it apart and dink around with it.  

The Donor - 80's Fontex Laptop w/Gray Double Shots and Qtronix KB-6000H Blue Cherry keyboard:

g81-1800 with cherry blacks?  Omg.  look at this item on ebay it shows MY switch for the same model number g81-1800 HAU!

I guess low serial number was from cherry black?
Yours has AT connector right?

Yep, when I bought them, I only popped caps on one and found MY's.  Since they had the same product numbers, I never even checked the second one.  Then I went to clean up the second one many months later, I was elated to discover black MX's.  The "West Germany" label is pretty cool too I think, makes it pre-1989

Hey, i was wrong, the one with blacks says G80, not G81, everything else is the same.  My bad.  I'll update my posts above.

Title: The Cherry Blue Blues
Post by: ricercar on Wed, 19 May 2010, 18:58:48

Quote from: didjamatic;171298

cherry blues ... some keys click loud, some sort of click and some sound almost like a linear switch with hardly any click at all.

Today I received a Cherry blue plate-mounted keyboard with the same audio problem. Few key switches have the expected Chery blue high-pitched click; most have a low-pitched, nearly inaudible click; some have no audible click at all. All keys operate electrically, and have a tactile click point and appear to be more stiff than the browns I'm accustomed to.

Is there a known cause of this sound reduction? Is is curable?

Should I be disappointed? I am.
