摘要

FIELD: transport.SUBSTANCE: set of invention relates to wing high-lift system devices, particularly, to switches, cases, levers and triggers. Wing high-lift system main control switch comprises interconnected command and drive control units. Command unit comprises two-arm lever equipped with handle with trigger. Said lever features zigzag configuration of arms connection and is fitted in command unit case to pivot on axle at intersection of central lengthwise axes of lever arms. Said arms are interconnected at 120-150 degrees to each other in the plane of turn. Command unit is connected with drive unit rocker by tender linkage connecting lever lower arm free end with rocker free end via two rotary hinges. Trigger comprises case consisting of two parts upper one being diverged and congruently fitted in lever handle seat. Command unit case is composed of dual box-like sector frame with side surfaces converging in wedge-like pattern towards bottom part and has two curvilinear plates.EFFECT: higher reliability and efficiency of control, higher safety, decreased weight and sizes.7 cl, 6 dwg
