Logitech G603 Switch Replacement

Flip the mouse onto its back.

Peel back the pads on the top and bottom of the mouse to reveal the four screws.

Remove the four screws with a small Philips screwdriver and set them aside.

Remove the battery plate and batteries.

Start at the same location as the previous step, and use your thumb to carefully pry the base from the shell of the mouse.

There will be two crevices that are attaching the base to the shell of the mouse.

Using a spudger, gently and carefully pry along the dotted red line marked in the first photo until the shell and the base are separated.

There will be two cables that need to be disconnected before completely separating the shell from the base.

To remove the ribbon cable, use your thumb and index finger to pinch the latch upwards.

Once the latch has been released, pull the cable out of its slot.

To remove the power cable, slowly and carefully wiggle the cable out of its socket either with your fingers, a spudger, or a flat head screwdriver.

Here, you will be able to see the underside location of the switches that need to be replaced.

Here, you can see the location of the next step which will be to unfasten the side button circuit board.

Locate the screw marked in the first photo. Remove it by using a Philips head screw driver and twisting in a counter-clockwise motion.

Use a screwdriver to remove the screw by twisting in a counter-clockwise motion.

Using a flat head screwdriver, push the latch upwards and into hole from which it protrudes until the cover loosens.

Using your index finger and thumb carefully displace the cover to reveal the switch.

The switch board will be secured by two screws. Using a Philips head screwdriver, remove the two screws using a counter-clockwise motion.

Using a spudger or a flat head screwdriver lift the circuit board from its slot.

Once there is enough room, pinch the board loose with your index finger and thumb

With the side board in hand, twist the board until there is enough room for the switch board to exit the gap located in the last photo.

Now that we have the first switch displaced, repeat steps 11-14 to displace the other.

Proceed to step 16 to remove the mouse switch from its hole

Now that the switches have been displaced, prepare your soldering equipment for the final steps.

Remove solder from the pin joints to displace the switch by using solder pump.

Once the residual soldering flux has been clean, begin soldering in the new switch into the board. Repeat steps 19 and 20 for the other switch.
