Comments on HMX Firecracker switches
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.
