Abstract
A breaker device is provided to prevent an insufficient engagement of electrodes. The device, according to the invention, is excellent in safety because of its construction in which a conductive path is located inside the casing 1 and is allowed to have a compact configuration of particularly low height because a handle 40 can be inclined to its resting position. When the handle 40 is inclined to the resting position while a movable electrode 31 is insufficiently engaged, engaging portions 77 come into contact with receiving portions 75 and a lever action works with the contact positions of the engaging portions 77 and the receiving portions 75 as a fulcrum. As a result, a rotating force applied to an operable portion 40A is translated into a downward acting engaging force applied to the movable electrode 31 via rotation center shafts 45 and a mount body 35. In other words, since the movable electrode 31 is brought into its properly engaged state by inclining the handle 40 to the resting position, the insufficient engagement of the movable electrode 31 can be prevented.
