Comments on HMX Puppy switches | Comments on HMX Firecracker 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. | Enter the HMX Firecracker, a tactile switch designed by yowzer, a fellow tactile enthusiast. A switch the New York Times calls a revelation and HMX calls give me your freight forwarding address. Feel: A snappy and slightly pronounced bump. Sound: Kinda deep kinda clacky – KeebzNCables. The HMX Firecracker Tactile switch is designed by our dear friend Yowzers. These amazing switches feature a P-shaped tactile bump, which makes them super satisfying to type with. Material-wise, this is the first HMX tactile switch that uses a POK stem. Paired with the nylon housing, the POK stem creates a full, clacky, but not overly loud bottom-out sound – Unikeys. |
