[Solved] Experiencing Double-Click Issue with Logitech M515 Wireless Mouse - Repair or Replace?

As in the topic ... I have had a wireless mouse for less than a year Logitech M515 Wireless Mouse , was doing perfect until ... For a month now, an annoying thing has appeared, when he makes even a slight click, whether on the left or right button, the system reads it as a double click - and more and more often. Selecting the text holding the mouse button is also a problem, because at some point in selecting everything breaks off and I have to repeat it several times to finally manage to copy or cut something. The fault is on the mouse, system or receiver side? Does it pay off to repair, or is it better to buy a new mouse?

Put another mouse and you will find out but rather a hardware problem on the mouse side, although it is strange that suddenly both buttons started to work like this.

Maybe it wasn't so noticeable that overnight, initially it rarely happened, but now it's very frustrating ... There is less problem with the right button than with the left button - probably due to less use. I feel sorry for this mouse, it was not the cheapest one ... but could it be repaired, would it make sense?

It is for repair, requires replacement of the microswitch inside.
I had it probably in the same model. (Logitech had several models in the same housing, all have the same problem)
I found an OMRON microswitch in my garbage and replaced it and the fault resolved.

When disassembling the mouse, you should disassemble it very carefully, there are two small springs that can get lost accidentally.
Two screws to remove are under the front slide.

If you want to look for a tutorial on how to undress it, google and "logitech double click problem"
If you do not have manual skills to solder, you can try to disassemble the microswitch yourself and regenerate it according to the tutorial -> Link

I don't know much about electronics .... How much does such a microswitch replacement cost? Any small services can take care of this? Will someone recommend something in Krakow?

I suggest going to the point where they repair laptops / phones / TVs
Ask how much it will cost to replace the microswitch if you bring only the board from the mouse
They should agree to the exchange for PLN 20 - it will take 10 minutes of work.
Provided you get him a microswitch - or some "donor" microswitch.

The microswitch number used in this mouse is: OMRON D2FC-F-7N
But for my eyes, any standard fits
If you want a photo of the microswitch and the place where these little springs appear, I can insert them in the evening when I have a telephone cable.

Hmm, this equipment should probably be available in some electronics store? If so, it would be appropriate for me to go ask and, as you say, hit a site to get them to do it. I'd rather not touch it with my paws myself - 99% I would have spoiled the whole mouse

For me, unscrewing (for the first time) and assembling after soldering took 10 minutes.
So I don't think it would take them any longer on the site.
2 screws are under the front slide, two under the sticker behind the batteries.

It is possible that you do not need to replace, Logitech mice had the problem that the soldering points of the buttons were breaking. It is enough to correct them with a soldering iron and check if the traces have not been broken.

A moment ago I had the same problem with this mouse. Here is the solution:

it worked for me.

I will conquer the topic because I have a similar problem. Will the OMRON D2FC-F-7N microswitch described here be suitable for Logitech v450 mice?

A very common problem, I did it several times at home with different mice.

The problem is the wear of the microswitch (more often) or the rubbing of the plastic part of the housing that presses on the microswitch, which has a recess in it for a fraction of a millimeter. This recess means that when pressing the button with the same force, the microswitch is actually pressed less.

Solutions:
1) Economical - for the patient and meager:
Disassemble the microswitch, remove the plate from it, which tightens the internal mechanism and bend it a little so that its tension increases (when using this plate straightens and the tension decreases)

2) Rational and fast:
The entire microswitch should be desoldered and replaced with a new one. The microswitch can be purchased separately (recommended OMRON) or removed from another mouse, rather all of them are standardized in size. Desoldering may be more difficult if the PCB in the mouse is double-sided. Then, without a professional suction device, it may not be possible to remove the button.

In this way, I have just fixed the problem with the double-click and drag & drop in less than 10 minutes in my Logitech M505 mouse.
