Said slider enters the fixed case carrying cone engaged with split cylinder with its outer surface in contact with said case and end surface in contact with spring. Slider second end rests on different-length springs fitted one into another. Travel of slider and spring is defined as follows: h₁+h₂-h₄, h₃=h₅, where h₁ is the section of independent contraction of one spring; h₂ is the section of joint contraction of two springs; h₃ is the section of joint contraction of three springs; h₄ is travel of slider in cone; h₅ is the section of contraction of spring whereon cylinder rests.
