Abstract
that imparts a driving force to separate the contacts through the power transmission mechanism. A latch mechanism restricts movement of the power transmission mechanism, and a pull-out operation section releases the restriction of the power transmission mechanism by the latch mechanism. The pull-out operation section is arranged to oppose a first arm of a lever to rotate the first arm. The lever is arranged so that a tip of a second arm is able to engage with and rest on the latch mechanism, and release the restriction of the power transmission mechanism by the latch mechanism.
