KAILH GM4.0 GM8.0 Micro Switch 60M 80MLife Gaming Mouse Micro Switch 3 Pin Black Mice Left Right Button GM 4.0 8.0 (Red 4pcs GM4.0)

the HUGE trackball has a serious flaw with the left click failing in only a few short months, this switch soldered in perfectly and not only fixed the problem but gave the trackball a very satisfying click feel on the left click button now.

Switches work great! I had a problem with my left click getting sticky shortly after soldering them into a 502 Lightspeed. Taking the mouse apart again, with its seemingly endless amount of screws showed that the flux I had used crept its way into the switch gumming up the works. I flushed the switch with a Q-Tip dripping wet with 90% Iso. That fixed the issue and its back to healthy working order. The G502 lightspeed is known for its Double-clicking switches. These will get you fixed if you're not wanting to spend the 100+ on a replacement mouse. Worth the effort, keep track of your screw location. Some screws are quite hidden, don't force anything, be thorough.

They really do be clicking. I offered the GM red 4.0 I have large heavy hands and fingers and these have some resistance so you get a lot of tactile feedback which I love about these. Soldered in well and fixed my mouse’s double clicking. (Picture provided. I installed these into a Logitech G604, which they don’t make anymore and are hard to get. All in all, they seem decent quality and work after soldering.

Perfect drop in replacement for Logitech's failed double clicking switch.

I have two Logitech G604 mice that I absolutely love. I've used them for about 4 years now at work and at home. They were about $80 when I bought them, so I definitely didn't want to have to replace them when they suddenly started having click bouncing problems. I do a lot of soldering work at my job and figured it would be a pretty simple job (your mileage may vary). I replaced the switches in one and decided to compare them side-by-side. The G604 uses Japanese Omrons, but there is quite a bit of travel in the buttons before it actuates. The Kailh switches seem to actuate the very instant you apply force to them. They definitely feel premium. They are no more or less noisy than the Omrons and feel like they have close to the same actuation force. Overall, I'm happy with the purchase. It saved me lots of money on replacing my old mice, and they feel great!

These function great, for a good price, only issue is that they each are tuned a little differently enough for there to be an audible difference in click. Kind of annoying, but as long as you check the noise they make beforehand and match them up, you should be fine

Worked perfectly for my Logitech!

Used to repair a trackball mouse. Worked as expected

Era desesperante trabajar con el problema de "Double Click" que tenía mi mouse Logitech MX Anywhere 3 principalmente en el boton derecho. Asi es que de una vez reemplacé los dos botones por estos KAILH y santo remedio. Los interruptores que el mouse trae de fabrica tardaron 3 años en darme problemas, a ver cuanto duran estos KAILH, que por lo que he leido son bastante buenos. Apenas llevo 1 mes con este cambio

My Endgame XM1r started having double clicking and debouncing issues on the left mouse button. Rather than spend $80 and buy a new one, I just bought these switches instead. Replacing my old switches with these ones turned an $80 problem into a $15 one. Work like a charm now. The red switches are slightly heavier than the older ones but not a big deal!
