Inside the Nightsword RGB
The four feet under the main body of the mouse have to be removed to access four screws. Once removed, the Nightsword comes apart, but we only removed the top cover, leaving the side panels attached to the lower section. No wires connect the top to the bottom of the mouse, and we can see most of the mouse parts soldered to the PCB in the lower half.
Our first up-close look inside is under the left button, where the blue Omron D2FC-F-K(50M) is located. The Omron actuation is lighter than we expected and the click is soft. As for the pad switches at either end, they are used by the DPI buttons, are softer than the Omron, and are much less audible. As to the type of switch used for the scroll wheel, we cannot see it, nor could we with disassembly, as you will see more on later.
The page forward, page back, and the sniper button are all backed with pad switches too, but different ones than for the DPI buttons. These are much tougher to actuate and while there is a click, it is nearly muted completely. Typically this is where more disassembly happens, but that wasn't in the cards for us.
The pair of screws near the ribbon cable, holding the side PCB in place need to be removed to view all of the side switches, and also has to be removed to look under the main PCB. Since the screw is stripped, this is as deep as we could go with the teardown.
Directly behind the scroll wheel are a pair of pad switches on risers, which are used for the profile buttons. These are soft, requiring little force, and again, the click is somewhat muted.
There is no view of the optical sensor from above the PCB, but the guide shows an image of the PixArt PMW3391 installed, and we have no reason to doubt it's there. What we are showing is the NXP LPC11U58J, which is the same 32-bit ARMK Cortex-M0 processor used in the M55 RGB.
Our last image of the interior is where we cover the last pair of switches. There is a matching Omron under the right button, and the white stuff on top seems to be residue from the plunder that hits the blue part of the switch. Just inside of that, yet another pad switch is used, which requires medium force to use, and reports with a hollow sounding click.
The last four images, we wanted to take a tour around the Nightsword RGB so that you could enjoy it in all its glory once powered. We timed the images as colors pulsed in all of the RGB LED panels to get them all blue, and the look is quite spectacular. Of course, we cannot have form over function, and Corsair seems to have come up with a happy marriage of both.
