I have a fairly new Unicomp Spacesaver that has developed an odd noise on the Enter key. When the key is released and goes back to the up position, the buckling spring seems to vibrate a bit, making kind of a jingling sound, a little like a slinky. As the owner of several BS boards, I'm used to the springs occasionally making a slight ringing sound, but this is far louder and longer, making it much more noticeable and distracting.
If I pop the keycap off and back on again, the noise goes away, but returns after a couple of days. The spring does not look damaged or bent that I can see. Does anyone have any suggestions? I was thinking of maybe putting some kind of damping material at the top of the keycap to maybe hold the spring a little tighter but I don't want to ruin the feel of the key either.
