Comments on HMX K01 switches | Comments on HMX Hydra switches |
The HMX K01 tactile switch is HMX's first-ever light-tactile switch to be released. The smaller tactile bump creates a comfortable typing feel with moderate tactile feedback, which is optimal for long-term typing duty and daily use. Technically, these are a long pole switch, but the stem pole is not extended by much; A 3.8mm travel distance makes the bottom out solid but not abrupt. Material-wise, we went with the classic non-modified PA66 housing and POM stem for the K01 light tactile switch; Such material choice maintains the classic HMX clack and doesn't make the switch sound overly loud and high-pitched. They sound clean and crisp overall, and I don't have to tell you how pleasant they will sound on your keyboard. The top housing comes with a matted texture just like the HMX Sonja and Sonja HC switches to create a grainy, scratchy feeling during typing. Important to note: When buying X90 or more switches, they will come in our brand-new switch container – Unikeys. | The HMX Hydra tactile switch is designed by XLLAB and features a big almost D-shaped tactile bump similar to Retro J. It is an attempt to replicate the classic Gateron Type R's D-shaped bump, but with a touch of the signature HMX clacky sound profile and fantastic stem wobble control. Thanks to the P2 bottom housing, the Hydra switches are one of the clackiest HMX tactile switches so far – Unikeys. |
