ABSTRACT:
Fixed electrodes 40 and terminals 30 are mounted on a casing main body 21 of a breaker device 10 with bolts 50. Each terminal 30 is firmly fixed between the end surface of a spacer 52 fitted on the bolt 50 and a mount base 24 by a fastening force of the bolt 50, and each fixed electrode 40 is pressed against the terminal 30 by an elastic force of a spring washer 52 fitted around the spacer 51 and is mounted such that it can be inclined by deforming the spring washer 52 by a remaining deformation margin. Accordingly, when the fixed electrode 40 is pushed by the movable electrode 44, the inclinations of the fixed electrodes 40 are automatically adjusted to reduce a sliding resistance which acts between the movable electrode 44 and the fixed electrode 40, thereby facilitating the switching operation.
