Abstract

Provided are a switchgear for which the contact parting time is reduced while stably maintaining the spring force of an interrupt spring and a mechanism for operating the switchgear. This mechanism has a main lever (11) that upon receiving the spring force released by the interrupt spring (12) when making a transition to an interrupting operation rotates so as to pull a movable contact away from a facing contact. A sub lever (71) fixed to an axially rotatable sub shaft (70) is connected to the main lever (11). A single latch lever (72) having a roller (72a) attached to the front end is fixed to the sub shaft (70). The latch lever (72) is prevented from rotating by a single intervening latch section (91) which is provided on the movement trajectory of the roller (72a). A weight (93) is pressed against the latch section (91) in a withdrawable manner whereby the weight (93) is pushed away by an actuator (21) so as to allow the latch section (91) to rotate to retreat from the trajectory of the roller (72a).
