Atari 800xl - Alps keyboard microswitch

Recommended Posts

Hi!

 

I've been on a lookout for Atari 800xl with an Alps keyboard. Finally found one (Untested).

 

Computer works, but the switch under the Shift Key is cracked and it sticks when pressed.

 

Does anyone sell these switches? I have a lot of loose keys for Atari 800 that I can provide in exchange or I can purchase with paypal.

I also have an Atari 800XL with ALPS switches, like those: https://deskthority.net/wiki/Alps_SKFL_series

 

Sadly, I have two switches that don't make contact all the time and one switch (at the letter "L") that sometimes makes contact when not actually pressed, filling the screen with "LLLLL..."

 

I have never seen those on sale, perhaps someone knows a cheap switch that could be adapted to replace the failing ones.

Picture is attached, thank you

I thought the Key-cap can be pulled-up? There is a metallic "guide" on the Shift key that's not present on most of the other keys.

I think the switches are the same for all keys.

I haven't de-soldered any of the keys on this keyboard, so I'm not sure how big of a deal it is to remove just the switch?

 

They key-cap will not stay with the switch, if you pull it up and wiggle the little metal out.

You just want me to de-solder the switch? Is the keycap going to stay with the switch. It looks like there is some kind of attachment on the key.

That's a good find. I also wonder if we could somehow use switches like in this ebay listing?

Well, does not ship to my country... and I think those are "clicky" and the ones in my atari are silent ("linear").

 

But yes, perhaps a different ALPS switch could work.

 

Most switches in aliexpress are "cherry type", like this https://www.aliexpress.com/item/New-10Pcs-KeyCaps-3-Pin-Dust-proof-Mechanical-Switch-for-Gateron-for-Cherry-MX-hot/32882945229.html

 

Perhaps this would work? https://www.aliexpress.com/item/10PCS-LOT-Imported-original-Japanese-ALPS-computer-keyboard-switch-key-switch-12-12-5-reset-4/32842709946.html

Hello Bob, I did de-solder my defective switch, it took me less than 5 minutes (I"m not even skilled at soldering). If you want to sell me a switch you de-solder or part of a keyboard, I'd be willing to pay to save my keyboard. I'm attaching a picture of the switch after it has been de-soldered. Please let me know if you have 1 or a couple for sale.

 

Thanks, Andrew

DMSC: I have some spare switches, but I'm not sure about shipping costs. PM me.


Can the switches available at this auction be replacements for those used by Atari?
