FIELD: electrical engineering.
SUBSTANCE: proposed draw-out equipment unit has control device disposed on its face control panel and designed to open or close auxiliary make-break contacts. Gate equipped with contact unit is shifted by means of link gear that has link body with worm helical line circuit. Section of worm helical line circuit has lower pitch and provides for closing auxiliary make-break contacts applying low forces for shaft control.
EFFECT: facilitated control of auxiliary make-break contacts.
