Comments on HMX Firecracker switches | Comments on BSUN Mozzarella Cheese 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. | Keys in Cheese Studio has done it again. This time, an interesting mid‑leaning tactile that can move toward clacky or thocky depending on configuration. Closest comparison would be newer‑generation HMX tactiles: quite poppy, a bit bright, but mostly mid‑toned – SerpentKeys. Mozzarella Cheese Switches by Keys in Studio and BSUN are tactile switches with a mid-leaning tactility that have quite a neutral sound profile, accentuated by the keyboard configuration – Divinikey. |
