Claims

[Scope of utility model registration request]

A pair of fixed iron cores each having an operating coil wound thereon and arranged side by side, a movable operating iron core disposed at one end of the fixed iron cores so as to face them and functioning as a vacuum valve opening/closing operation member, and a movable operating iron core for operating the operating coil. A charging yoke is arranged on the other end side of both fixed iron cores so as to magnetically communicate with both fixed iron cores in order to form a charging magnetic path through the movable iron core, and a charging yoke is arranged to connect the fixed iron cores to the operating movable iron core. An opening spring that acts to open the poles, a movable tripping iron core disposed so as to face the other end of only one of the two fixed iron cores, and the closing magnet through the tripping movable iron core. a trip yoke running in the one fixed iron core in a direction perpendicular to the other fixed iron core and terminating opposite to the trip movable iron core to form a trip magnetic path perpendicular to the trip magnetic path; a return spring that applies a return force to the operating movable iron core; and a return spring that applies a return force to the operating movable iron core, and the operating movable iron core that is brought to the closing position against the spring force of the opening spring by energizing both the operating coils. The mechanical latch of the movable operating iron core is released by the movable tripping iron core which is attracted against the spring force of the return spring by energizing the operating coil on the one fixed iron core. A vacuum switch operating device equipped with a latch mechanism.
