Abstract (en)
[origin: EP0709868A1] The invention concerns a circuit breaker in which its movable member (13) made up of a movable conductor (13b) such as a thin metal plate is sufficiently high in mechanical strength, and a movable contact (13a) welded to the movable conductor (13b) is positively secured to the latter, showing high welding strength, and which is low in manufacturing cost. The movable member (13) is designed as follows: One end portion of the movable conductor (13b) made of the metal plate is formed into a plate-shaped portion (13e) having a predetermined width, and the movable contact (13a) is provided on the plate-shaped portion (13e). The movable conductor (13b) is twisted 90 DEG at the middle so that its remaining portion is perpendicular to the bottom of the casing. <IMAGE>
