Enter key stuck and not bouncing back..

[fatchoi]

Hi all, recently I built a faceu 60% board. However, when I put the key caps on, there is a big problem with my enter key. The enter key is a standard one with cherry style stab.

I installed my SP dolch enter key but upon the enter just sinks and stuck, not bouncing back...

I tried installing another enter key I have (Poker x key set) and it works well.

Can anyone please help and give some advice?

Edit: forgot to mention my space bar is also working well. My backspace and the 2 shifts are split into 2 keys, so they don't have stab, thus no problem at all.

Does the second key you tested utilize the stab?

The enter key that sticks - is it flag?  Can you put it on a flat surface and see if it wobbles from side to side.

Cherry stabilisers are notorious for low tolerance of warped keys

Yes, it does.

Just tried, the key is flat. I indeed also tried the other backspace cap of the same width (dsa cap, so it's compatible) but also fail to work.

I guess the distance of the 3 stems of the SP cap (problematic one) is shorter than my poker (working great)...



Thanks both for replying. Hope I won't end up desoldering every switch and LEDs... My board has a plate and only pcb mounted stab is supported.
It's impossible to easily swap or add stab.

Next step is to measure, as accurately as you can, the spacing between the stems on both enter keys.

It could take only 0.5mm difference to make the key stick.

Assuming you didn't put the stabs in Backwards..


put the stabs in.. and check for wobble

And check if the 3 holes in the cap are pointing straight down..    you may need to into the stab to compensate.

Picture talks... 




Seems that there is tiny difference in the stem.

I followed someone else's assembly guide when I assemble the board. And I think it's impossible to invert the stab upside down because the holes in PCB are different between the top and the bottom. The wire is above the switch.

I think the caps' stem are vertical, because I tried another DSA profile backspace key of the same SP dolch set. Same problem..

There is a slight skewed angle here, so I can't really accurately measure the difference, but it does appear to be enough to cause a problem at the front of the key's base.

put stabs into all three holes   ,  then lay a metal ruler ontop  and then on the side,   if it is the Stem,  you should see some spaces between the ruler and the stabs..
