    • To keep it out of the way, wrap the USB cable using the integrated Velcro cable tie

    • If the Velcro cable tie is damaged or missing, a twist tie works just as well

    • Remove the weight cover from the bottom of the mouse by lifting it up by the mouse foot.

    • Using a heat gun (set to low), heat up the three mouse feet for several seconds each.

    • Slide an opening pick under both the mouse feet and the adhesive underneath it.

    • If done correctly, you should be able to peel off the mouse feet with the adhesive still attached.

    • If the adhesive does not come off with the feet you can scrape it off with a spudger.

    • Insert the flat end of a plastic spudger into the area indicated between the top and bottom shells.

    • The two halves of the mouse will split almost completely apart with very little force.

    • Do not attempt to pull apart the two halves just yet.

    • Insert the flat end of a plastic spudger between the top and bottom shells on the left side of the mouse, next to the left click.

    • The top and bottom shells will completely separate, allowing the top shell to be lifted off.

    • Use caution to avoid snapping the plastic clips holding the two halves together.

    • Using the flat end of a plastic spudger, carefully lift up both sides of the lock that secures the ribbon cable.

    • With the lock released, the ribbon cable should easily be removed from the connector.

    • Do not use too much force releasing the lock, otherwise the connector may be damaged.

    • Remove the side board by pulling it straight out to access the ribbon cable connector.

    • Using the same technique that was used with the Hero sensor ribbon cable connector, disengage the cable lock.

    • Remove the ribbon cable with the side board.

What’s that button near at the spring on top. Is that a middle mouse button? (yellow button thing at the middle at the top)

Nicholin V - Ответить

You are correct, that is the middle mouse button

What’s a good replacement switch for the 2 main left/right buttons? They say OMRON 3159C21 D2FC-F-K

Anthony Clark - Ответить

That’s a good switch to replace them with

Me personally, I like to pull the switches off of other mice, like those rebranded Logitech ones that are bundled with some computers

The G502 is easy enough to pull apart and put back together that I don't mind replacing the switches on occasion

spslizer -

@spslizer sorry I wasn’t clearer before: the switches that are on the primary/secondary buttons are the OMRON D2FC-F-K and the primary switch has failed. I’m replacing them both with Kailh GM 8.0 switches since they seemed to have a good reputation.

I definitely need to study desoldering more though, I am having a lot of trouble removing the bad switches!!

Anthony Clark - Ответить

I find that the easiest way to desolder them is to heat up the existing solder, add more new solder, then use a desolder vacuum pump as close as you can to the pin while your iron is still there. If there's still a small residual amount “tacking” it on, heat up the pad around the hole and then wiggle the switch around

It helps to have a helping hands station and a pair of tweezers or hemostats to hold the switch, as the switch and pads will get hot

Hi! I was just wondering if you knew the dimensions of the screw! I lost one when I took it apart and now my right click is a little bit wonky. Thanks!

Sophie T - Ответить

Hi Sophie. I unfortunately cannot find the shell and screws of one of these mice.

I would recommend trying one of the shell screws from one of the bottom holes and put it in the hole under the right click or the front hole, depending on which is missing

The microswitch may also be on its way out; a “bounce” click when you click and hold is a good indication of this

Disregard the first part of my comment. I have the measurements from the shell screws

On mine they are M2x10.25mm screws. The head looks to be about 3.25mm wide

spslizer -

Can you plz let me know the dimensions of yellow button (middle click button)? Thanks.

Mujtaba Ali Panjwani - Ответить

From my measurements with a non-digital caliper, it is approximately 9.5mm square, with a height of approximately 1mm

If measuring from the outside where the component is indented for the contacts, it is about 8.5mm. The button looks almost like a very stubby “+” symbol. I hope this information helps!

Gracias! pude cambiar los botones de mouse sin problema
