The battery charge is enough for 30-40 days of work. We disassemble, pull out the board, solder the old ones, solder the new ones, clean the board, assemble it in the reverse order. This is a micro-review of microswitches. Two of the same half-dead always lie at the ready. Next is the replacement process itself.
To be honest, I didn’t look at brands like Omron because of the cost, but chose what was cheaper. The parcel came surprisingly quickly – in 15 days. In the mouse I use old AA batteries with a small residual capacity. How long they will work – let’s see, the time has come. There are no remarks in appearance – there is no flash, the conclusions are of the same size, the inscriptions are clear. A week of daily work – there were no false positives. It feels like the sound of the new mikriks is a little louder, not even that – a little louder.
In any case, the spares are already lying around, changing them is a matter of 10 minutes.
The search for donors began immediately. According to the sound of the clatter, the least loud ones were selected, although this is purely subjective – it is very difficult to determine by ear. Ordinary white metal, not coated with anything. P.P.S. According to a fair comment from users, I dismantled one button – no silver / gold-plated contacts were found.
