Abstract

A pivotable control level disposed between a pair of spaced plates, with a motion resisting element mounted on the lever and compressed by the plates to provide a constant resistive force or "feel" to the system operator. A separate adjusting mechanism selectively increases or decreases the amount of compression exerted by the plates on the element to either increase or decrease the resistive force felt by the operator.
