Corsair OPX Key switches

Corsair OPX Key switches

Corsair OPX optical switches are used in the Corsair K65 RGB Pro Mini. They are Fast Linear – with 45g actuation force, 1.0mm actuation, and 3.2mm travel, and guaranteed 150 million keystrokes. So, in general, their characteristics are similar to the Reds, but with lower actuation (1, not 2 mm) and total travel (3.2, not 4 mm).

Mechanical switches give you a more perceptible feel than the rubber membrane used in cheaper keyboards. Mechanical keyboards are gaining an increasing share of the gaming peripherals market quickly. The performance is good, and the reliability is outstanding, so what more can you ask for? Aaah, yes – full key rollover (but can you push more than ten buttons simultaneously?) and anti-ghosting.
The so-called Reds (OPX used here have similar characteristics) are possibly the best choice for first-time buyers.

 
Why’s that? The crucial features are 45 g of actuation force, linear response, and rapid bounce back. If you use a keyboard like that, you get used to typing faster without bottoming out the keys. Still, some switches work better for writing, e.g., MX Browns or Blues.   

The MTBF is 150 million strokes, so it’s a massive figure. Still, you’ve got a warranty if something breaks. The keycaps are made from PBT (so not the worse ABS, which is less reliable/resistant), and the per-key RGB backlighting makes it look good.
