Abstract
A sealed electric switch assembly comprises a magnetic control assembly having first and second magnetic members which is mounted to a top wall of a sealed casing, and an elongated plate having third and fourth magnetic members which is mounted oppositely to the first and second magnetic members so that the elongated plate member can be attracted and repulsed magnetically by the magnetic control assembly. A linkage mechanism is mounted adjacent to the elongated plate member for moving a movable contact of a movable arm to connect and disconnect with a stationary contact. A rotary assembly and a tripping assembly are mounted above the linkage mechanism and over an electromagnet.
