I have a Logitech M570 Wireless Trackball. I’ve had it for a few years, and love it. Recently I’ve noticed the the right mouse button has click issues. Sometimes it will right-click and act like a double click. Sometimes it will stick. This was a problem during gaming, working in Excel and while completing other tasks.
Finally, I was tired of this problem, so I did a search. Amazingly, this is a huge problem. The Logitech forums are littered with complaints. What is the problem? It seems to be the microswitches Logitech is using are not holding up. Many users are able to contact Logitech and have the mouse replaced under warranty, but the Logitech hasn’t officially addressed the problem.
How to fix the M570 Wireless Trackball right click
There doesn’t seem to be a consensus on fixing this problem. A site called Red Ferret has an article on repairing a switch in a Logitech mouse (not the M570) (http://www.redferret.net/?p=31008)
The symptoms are that the mouse click delivers two clicks for one press, which can be extremely annoying and renders the mouse unworkable for important tasks. This time, however, instead of consigning the device to the trash and buying another, we decided to see if we could solve the situation with a bit of DIY. And the answer is yes!
A quick search on Google revealed that other more intrepid souls had managed to fix their own meeces, and so we got to work on two ‘dead’ mice lying around in Ferret Towers, a Logitech M705 and an older MX Revolution. The first thing to note is that the culprit is tiny, a sliver of copper which can’t be worth more than £0.02p.
Their solution is to re-bend the spring or “sliver of copper” and they even have a video showing how to fix this.
Logitech Mouse Double Click Problem and How To Fix It
While this seems like a cheap fix, it does seem annoying to tear the whole thing apart just to tweak that spring. Why not replace the switch with a new one?
What switch is in the M570 and what do we replace it with? The consensus is Omron makes the best switches, but no one really made a distinction on what is the “best” switch for a mouse button. This forum lists the Omron switches and lists the D2F-01F as one of the better switches. Interestingly, it seems the Logitech uses Omron switches in many of their products, like the trackball in this post that clearly has a DF-01F-T switch.
Is the M570 mouse worth fixing or should we just buy a new one?
The M570 sells new on Amazon for about $40. A new switch is only a couple dollars on ebay, but the labor to put it in is probably an hour and some soldering. So, is it worth trying to fix? That’s a tough question. There are reports that some users are only getting a few months out of the M570 before experiencing the problem. If that’s true, it might be worth fixing, but if Logitech will warranty the trackball, buying a new one may be a better option.
Finally, is Logitech to blame for this problem? Is there something they should do? It appears that Logitech is using the best switches available in their products, unless the M570 has a non-Omron switch. Maybe these switches just won’t stand up to the kind of abuse the users are giving them. Maybe a mouse only has a lifespan of a few months for some people and a couple years for others, at least until someone builds a better switch.
