Abstract (en)

Disclosed are a switching mechanism for an air circuit breaker, and toggle links thereof capable of preventing interference or collision therebetween while the air circuit breaker performs a closing operation and an opening operation. The toggle links comprise: a first link (29) configured to be rotatable; a second link (34) having one end connected to the first link, rotatable by a discharging elastic energy of a closing spring, and having one pair of extension portions (55) extended towards the first link so as to prevent interference with the first link by interposing the first link therebetween; and a third link (35) having one end connected to the second link, and rotated together with the second link, for moving the movable contactor to the closing position.
