FIELD: circuit-opening devices including those used for sensing relays (warning devices) of automatic control, protective, and warning systems. SUBSTANCE: switch has movable and fixed strips with contacts mounted in insulating base. Operating arm is mounted in blade-type supports of bracket and auxiliary arm, in movable strip, both joined together through cylindrical operating spring. Device is characterized in that it is provided with conducting flexible spring one of whose ends is secured between bracket and fixed strip and other end is clamped between contact and fixed strip. Movable strip is mounted in blade-type supports of bracket and conducting flexible strip has corrugated section in center. Current loads can be raised to 20 A. EFFECT: improved current loads under vibration and impact loads. 3 cl, 1 dwg øøø1
