PROBLEM TO BE SOLVED: To achieve stabilized switching operation while suppressing the occurrence of deflection or torsion for a shaft at the time of driving, without increasing the weight, cost or size of a switchgear.SOLUTION: The electromagnetic operation switchgear includes an electromagnetic operation device having a coil for bringing a movable core and a fixed core into contact with each other or separating them from each other depending on an electromagnetic force, a switch in which contacts are separated from each other or brought into contact with each other by a driving force incident to an electromagnetic force generated from the electromagnetic operation device through a link mechanism consisting of a movable rod, a lever, a shaft and an insulation rod, a bearing bracket for supporting the shaft, and a housing frame for housing and supporting them. The bearing bracket is disposed on the inside of the shaft end, and is secured to the housing frame. |
