摘要

FIELD: electrical instrumentation engineering; electrified consists using multiposition switch groups. ^ SUBSTANCE: proposed multiposition switch has electrical operating mechanism and frame assembled of four longitudinal strips for securing cam contactors and three side frames that carry seats for rotation of first and intermediate shafts, and camshaft. All shafts are coupled together through transmission gears in the form of pair of elliptical gear wheels and two pairs of cylindrical gears. Mounted in seats for first and intermediate shafts are supports made in the form of bushings and devices for their locking on side frames. Each bushing has inner opening offset relative to center of its outer diameter, respective seat diameter in side frame being greater than outer diameter of bushing. ^ EFFECT: facilitated adjustment and enhanced reliability of multiposition switch. ^ 1 cl, 2 dwg
