there isn't a spring, the clear stem engages directly with the micro-switch. This looks like a whit rectangle in a black frame soldered onto the circuit-board. there is supposed to be a small bit of metal on top which when pressed by the stem will bend and push the micro switch, but will spring back to its bent state when released. this may have come off. But the main problem seems to be with the metal circle inside the micro switch. The way the switch works is this: there are to contacts on the circuit board, not quite touching. when connected, they complete the circuit. sitting above the contacts (housed in the black frame and kept in place by the white film) is a small, slightly convex circle of metal. When the stem of the transparent button presses it down, it "clicks" and becomes concave, and connects the two contacts. When the button is released, it should spring back to concave, but sometimes it gets stuck. then we end up with either an extremely sensitive or permanently engaged switch.
Mine doesn't appear to have any extra blue plastic, so that's weird?
Thanks for for the info on the stem! I'm guessing my little metal bit got bent when I dropped it on the concrete locker room floor - it was one of those moments that in retrospect happened in slow motion with the switch side hitting the floor with a sickening crack....I'll probably have to send mine in for a proper repair, tho it seems to be better than it was at first. I did email TWC but I think I may have used the wrong email address, so will try the one posted above! I immediately ordered another one overnight as I couldn't gear the thought of being without it! I seriously think I have some obsession issues with this gadget, it's so cool! Anyone else feel such attachment to their Sonic? (Ie pleading for Yes answers so I don't feel like a basket case, lol!).
As for the additional inner blue strip, I took a pic so everyone could better understand what I'm describing since it would be impossible to see unless you take it apart:


and here's both strip inserts actually removed. The one with the little notched end is the hidden side. I just can't figure out the purpose of it, even the notch doesn't seem to serve any purpose, so I don't understand why they went to te expense of sculpting, molding and manufacturing and assembling this extra piece! I also noted the strip that is visible has a white coating on the inner side, presumably to make the translucent blue pop as it does. The alt side does not have this, so I thought maybe they were swappable so the led indicator lights might show thru with the alt insert in place to give a sort of visual indicator of power or readings levels for the Doctor to read - but the notched end sort of spoils this theory as if you swap the sides the notch leaves an open bit towards the bottom end. Absolutely bewildering!
Funny how such a small thing can obsess one. Hopefully someone from TWC will reveal its purpose!
