Know before you buy
Yes, these are 5-pin PCB mount switches, which are compatible with most modern hot-swap mechanical keyboards. If your board only supports 3-pin switches, you can simply clip the two extra plastic legs off the bottom of the switch.
No, the HMX Poro switches come factory-lubricated for a smooth, consistent feel right out of the box. They are designed to perform optimally without any additional modification.
The 45g actuation force is considered a light-to-medium weight, making it very comfortable for extended typing or gaming. It provides enough resistance to prevent accidental keypresses while remaining light enough to reduce finger fatigue.
Yes, these switches feature a standard MX-style cross stem, making them compatible with the vast majority of aftermarket mechanical keyboard keycap sets.
The P3 nylon blend top housing is chosen for its durability and sound profile, while the PA30 bottom housing provides a stable, smooth base for the stem. This combination is specifically engineered to balance structural integrity with a refined, consistent linear keystroke.
Since each pack contains 36 switches, you would need three packs for a standard full-sized 104-key keyboard. A 65% or 75% layout typically requires two packs.
