Comments on HMX Puppy switches | Comments on HMX Longjing S switches |
A strong, well-tuned tactile with a warmer character. The bump is pronounced, but cleanly guided and not scratchy. Sound-wise, it leans more deep and thocky, setting it apart from many brighter HMX switches. A strong choice for anyone who wants noticeable feedback paired with a fuller, more pleasant sound – MonacoKeys. | The HMX Longjing S tactile switch is the successor of the Gateron Longjing tactile switches. Material-wise, these two switches don't differ much, but HMX's light tactile molds make them feel and sound drastically different. Longjing S tactile switch is similar to the HMX K01 tactile switch, which delivers a mid-clacky bottom-out sound; The tactile bump is on the smaller side and similar in size to the Cherry Brown switches – Unikeys. If you're a fan of HMX K01, you'll like these too… primarily because they're pretty much a recolor. Made with a PA66 top/bottom paired with a POM stem. The tactile bump is very light with these, similar to what you would feel with Cherry Browns. Sound wise, very similar if not identical to K01. A clean, crisp clacky sound profile that isn't too loud. No ping, crunching, or any other weird noises. These are some of the best light tactiles HMX offers. Right up there with Yamatake and Valerians. I would highly recommend! – @keyboard_dad. The HMX LongJing Tea S Tactile Switch is the next evolution of the classic Gateron Longjing tactile switches. With HMX’s new tactile molds give the Longjing S a noticeably different feel and sound – LumeKeebs. |
