I just can't slide the controller off my beamspring.The condition is pristine Including the foam, but the controller just won't slide off. Any suggestions?

They can be quite stiff. Easy does it, each side in turns. They’ve been mated for decades, remember. Separation is quite the upheaval.

Wow you're not kidding, that thing looks great.

The peculiar thing is that one of the space-bar switches is missing a fly plate.

Tried that several times, it wouldn't budge. Any other ideas ?

The keyboard has clearly been serviced, but they forgot to fix the flyplate and for whatever reason removed and didn't replace the flyplate...
I think it's supposed to be like that, no? I thought the spacebar had one functional switch and one dummy switch to act as a stabilizer.

That does make sense, I don't see why two switches should trigger the space-bar.

Now some help me with more ideas on how to get the controller off please ....

Clamp the pcb down and gently tap the edge of the connector on each side with a soft plastic tool and a hammer maybe?

I'd use mineral oil and drip it into the connector of the controller (use a syringe if you have one at hand). Shake it from time to time and let it sit for a few hours. I bet some of the contacts are corroded and it just takes some force to get them off.

Tried that. Maybe I am being too fragile, but the edge connector didn't budge even one bit....

I have WD40, but I've heard it can disintegrate plastic. Not sure what I should do ?

Try spraying a bit of contact cleaner in there , it could be corroded .

The spacebar uses only one switch but it has 2 sliders. The other slider never had a foot, which means every beamspring keyboard basically comes with 1 completely unused beamspring.

Now I wouldn't really say the beamsprings wear out, but you might consider swapping that slider with the other spacebar one.

I would do this, if its corroded they could be stuck together and when you pull it could rip up the contacts

I'm not sure about the beams themselves, but these switches in whole do wear out. I have a pretty heavily used beamspring 3278 as my daily driver and the heavily used keys(can see by the shine on caps. No texture left whatsoever...)have different characteristics when compared to those basically unused.

Those with less use have one very sharp and clear click, you know what I'm saying , but those heavily used have a bunch of more soft and less pronounce click combined into one less satisfying click. All concentrated together. I dont know how to describe that feeling. It's like dropping glass bottles. The better ones are like dropping one big bottle and the worse ones are dropping a bunch of smaller bottle and they hit the floor at the same time. Hope I'm conveying my visuals here.(probably not)

Now this is only apparent when you are pressing very gently and slowly. Usually theres no different when just typing at normal speed. And yes I did check the spring to make sure there's nothing wrong with them.

It could just be the fly plate getting bent out of shape. Though, I'm not sure if that's realistic. In any case, I mention it because it's something that you can easily adjust.

I can confirm that all the keys feel and sound the same on my beamspring.

Also I didn't any notice any rust anywhere on the keyboard.

All the springs, the metal stems, the body is absolutely flawless.

I checked the connector closely, there doesn't appear to be any corrosion. It's highly unlikely that the connectors will be the only part to have corrosion.

I've been going at it for the past hour with a hammer, still no luck.

Now I am contemplating the below:

1. Solder out the edge connector from the original controller board

2. Leave the controller as is, and solder in a CY8CKIT-059 directly on to the back of the edge connector (where the pins are exposed)

What do you guys think.

I am not too sure if pouring oil into the connector is a good idea....?

Did anyone else have a stuff connector before ?

That's actually not a bad idea if it really won't budge. The modern stand-ins for that same connector part never quite fit correctly. And since yours it stuck anyways, you can be sure it's not going to move on you!

Maybe use some isopropyl alcohol instead of oil.

I checked my controller boards and the connectors and I believe the only thing that can cause this is corrosion. There is no screw etc. As you have said ... there is no corrosion anywhere else on the board, it is very odd.
I wouldn't use the original connector, as it is super hard to solder to the XWhatsit PCB. Maybe breaking the plastic of the top off would help (if done carefully).

So in the end I just use a long screwdriver to act as a lever between the edge connector and the PCB and pushed it out. It took quite a bit of force but it eventually came loose and I was able to get it off!!!

I guess the parts had just been together so long that they got stuck together. You just broke up a 40 year marriage!

Looks like a 3278 PCB with a notch - looks great. Do you have a Num-Pad as well?

Interesting. I see holes on the pins which does not exist on mine.

Yeah I did saw that but i am not sure that's the case with mine since i disassembled all switches for cleaning and reassemble them randomly. However, I will check on that when i got home and will probably make a thread about it.

You can buy new edge connectors that will fit , its a standard size.

When your using the replacement controller make sure its grounded properly , interesting failures cccccaaaaaaaaaaaannnnnnnn result from bad grounding :D. ( if you know what i mean , hint hint :D)

Did you buy this from a seller from Austria?
