1 The specifications regarding trigger forces apply only to steel versions, not to spring washers made of stainless steel, and are based on our own tests using a bright steel shaft made from materials 1.1151 or 1.0715, each in tolerance class h11.
We recommend customer-side tests, as roughness or work hardening of the steel shaft, among other factors, can lead to different values.
