FIELD: military equipment, in particular, weapon control systems. SUBSTANCE: the laying control unit has a framework with two potentiometers positioned in two mutually perpendicular planes, clamp-shaped shaft with longitudinal grooves and cylindrical ends kinematically linked with the potentiometer shafts, handle with a hand control hinge located in the longitudinal groove of one of the shafts and with a compensator in the form of a half-cup spring-loaded from the inside and two rollers engaged with the inner walls of the clamp-shaped longitudinal groove of the other shaft. Press-fitted on the ends of the hinge are rolling bearings that are located over the outer races in the shaft longitudinal groove without any spacing. The rollers are made in the form of double-arm supporting coaxial cylinders, the diameter of whose extreme supports is less than the diameter of the roller middle section. V-shaped cavities are made in the handle and half-cup that are engaged with the supporting cylinders, and the middle sections of the rollers are engaged with the inner walls of the longitudinal groove of the clamp-shaped shaft.
