I have a Keychron K10 C3 Full-Size Mechanical Keyboard with Gateron G Pro Brown switches and an aluminum frame.
Recently, my left Ctrl key got stuck. When I removed the keycap and pressed the switch stem, it felt very weak, with little return force. I tested the right Ctrl key, and it felt much more responsive, so the issue seems isolated.
I suspect the spring may be misaligned or dry. I often carry the keyboard in my backpack with my laptop, so it's possible the key was pressed or knocked during transport, but I’m not entirely sure.
I plan to disassemble the keyboard, desolder the faulty switch, and open it to inspect whether I can repair the spring or if it needs to be replaced.
I also had a bigger idea — to replace all the switches with ones that have higher-tension springs or heavier actuation force, since I have a mild hand palsy. Sometimes, my fingers rest on the keys unintentionally, causing unwanted keypresses.
I'm very comfortable with soldering, so doing a full switch replacement isn’t an issue.
My questions:
Am I nuts for replacing all the switches?
What’s a good source for switches?
Should I just replace the faulty switch and move on?
Is it worth trying contact cleaner in case it's just debris in the switch?
Thanks in advance,
