Bench Readout — averaged across runs
Select a dome or slider test on the left.
Collapse Force, Snap Ratio, and Energy to Travel are read from the averaged press curve.

Method. Press and return strokes are recorded at 0.005 mm steps on a calibrated bench. Collapse is the tactile peak; Valley is the post-collapse minimum. Snap ratio = (Collapse − Valley) / Collapse × 100 — the dome-switch industry's tactility standard (higher = crisper; linear = 0%). Travel is detected where the bottom-out wall begins (press slope exceeds 300 g/mm past the valley). Energy to travel is the area under the press curve from 0 to Travel, in gf·mm — the honest single number for how heavy a dome feels across the whole stroke. Grams and gf·mm are rounded to whole numbers to match run-to-run repeatability; hover the chart for readings as recorded.
