Sealed electric switch assembly, especially for power switching

摘要

The switch assembly includes a magnetic control assembly having first and second magnetic parts which is mounted to a top wall of a sealed casing. An elongated plate having third and fourth magnetic parts is mounted opposite the first and second magnetic parts so that the elongated plate can be attracted and repulsed magnetically by the magnetic control assembly.- A linkage mechanism is mounted adjacent to the elongated plate 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
