ABSTRACT:
A breaker device excellent in safety and contained in a compact casing. In a casing 1, a pair of fixed electrodes 11a, 11b is projected, and a movable electrode 31, which is fitted with and detached from the fixed electrodes, is arranged. A handle 40 is inclinably supported by a supporting shaft 45. On the top surface of an upper casing 3, a pair of poles 70 is erected, and rectangular solid sliding projections 71 are projected, while guiding grooves 73 are formed in side faces of the handle 40. In each of the guiding grooves 73, an arc-shaped portion allowing the sliding projection 71 to rotate about the supporting shaft 45 is provided at an upper end of a linear portion which allows the sliding projection 71 only to slide therealong. When the movable electrode 31 is inserted with the handle being erected, the sliding projections are guided by the linear portions, while the handle 40, maintained in an erected state, is inserted. When both the electrodes are normally fitted, the sliding projections 71 reach the arc-shaped portions and relatively introduce thereinto, whereby the handle 40 can be inclined.
