FIELD: electrical engineering; switches with short contact travel, such as vacuum switches. SUBSTANCE: switch has contact system, turning lever with reset spring, and double-link mechanism one of whose ends is hinged to turning lever and other end is placed in slot for displacement therein when pawl is released. Midpoint of mechanism is engageable with pushrod; during free movement, it crosses dead point and is locked on fixed stop. EFFECT: improved design. 2 dwg
