I just replaced a faulty switch in my 18-month old Logitech M570 trackball, using switches harvested from an old Kensington Orbit, which has saved me at least 40 GBP on a replacement.
I am surprised that it has already begun to fail. My other older Logitech trackball has seen much more use and is still working fine. So now I wonder if anyone recognises the brands by the logo?
The red/black one on the left is from the Kensington, green/white with yellow clicky is stock:
Also it was a pain to remove the M570 switch, higher-temp lead-free solder and double-sided pads. :~
The sound they make is very different too. The Logitech switch has a quieter click but both feel the same.
Chloe, look in the mirror. What you see is a technician.
From Wikipedia: A technician is a worker in a field of technology who is proficient in the relevant skills and techniques, with a relatively practical understanding of the theoretical principles.
This thread sounds like flirting
But it’s normal, a gal who make these things is the dream girl of flashaholics
Edit: I forgot to mention, omron is a very good and reliable brand, I’ve been programming their programmable logic controllers, and used several automatization parts in machines worth some million €. So if the maker of the machine trusts omron, I trust omron too
Did you do those with your little S95? Looks good, easy to see what you’re talking about and I know that’s a very small subject. Makes a difference when the pic is clear enough to read the numbers on those little circuits and stuff (not that I have a clue what they are or anything)
Curiousity got the better of me and I took apart my old Logitech to find it has the same switches as the Kensington, with clearer writing “DM1”, made by Multicomp. I found a supplier selling them for 40p each ! So that’s handy if any of these fail.
Replaced a few micro switches on mice over the years, takes a certain de soldering technique, I usually take a tiny flat screwdriver and jam it under the switch then taking turns on all the legs I slow heat up and lever it off the board, of course I’ve had some practice on controller boards which have even smaller Micro switches.
If you have a solder sucker it helps as well.
Yes it does, especially if harvesting rare/obselete switches (ALPS CM, for example). I usually reflow some solder first, desolder pump, let it cool, repeat then braid and use a scalpel to help pry the switch off. An IC removal tool can help too, to avoid bending pins.
