Name the point on the curve
Operating force describes the force at the switch’s operating point under the manufacturer’s method. Initial force, tactile peak, return force and bottom-out force are different values. If a product page publishes only operating force, the other points remain unknown.
Keep tolerance attached
A published 45±15 gf range is not equivalent to an exact 45 gf measurement. The register preserves tolerance because two nominally similar products can have broad overlapping ranges.
Do not rebuild a curve from two numbers
Pre-travel and total travel can be located on a shared axis, but they do not reveal the force between those points. Keyswitch Lab does not invent a force–travel trace from operating force alone.
