Does anyone know where to get replacements for the buttons on the tbeam? I’ve worn out my center button and need to swap it out.
Thanks!
On ali search for “smd 2x4” or "smd 2x4x3.5 smd 2x4 - Buy smd 2x4 with free shipping on AliExpress
Hope you have good eyes! 
It is a bit of a task to un/re-solder them.
I got a bag from AliExpress a few months ago – 10 of them was $0.49
but shipping was another $5.49. :-o I can snail mail you a couple if you’d
like. They’ll certainly get to SF from TX in less time that from China.

That’s the search term! Thanks!
There’s a distributor near me that seems to have them but they carry two different types with two different footprints with the same dimensions. Could I ask you to take a picture of the top and button of the switch so I can make sure I get the right one?
They’re $0.29 / ea
Thanks for the offer to mail one, but with the picture I can walk in and pick it up tomorrow.
Cheers!

It’s the one with the plastic mounting holes, very good. Thanks so much!
Actually, those are two little “nubs” that stick into the PCB and not holes.
Good luck!
nubs that go into holes.
thanks!
Thanks! Replaced them today. Worked like a charm.
What ever plastic the button is made of is very low temperature. I had difficulty getting the soak temperature right on reflow so it wouldn’t melt. Probably didn’t preheat enough. Either way, works now.

Just knocked the 3D antenna (Bluetooth/WiFi) off my T-Beam. You think it was tough soldering those microswitches onto the board… HA HA HA
