ABSTRACT OF THE DISCLOSURE A power switch assembly has a horizontal supporting base, a circuit disconnector including a first supporting porcelain insulator vertically disposed on the supporting base, a stationary contractor supported by the free end of the first insulator, and a rod-shaped movable contractor separably engaged by the stationary contactor and pivotally secured to an operating mechanism located within a hollow terminal disposed at the free end of a second supporting porcelain insulator vertically disposed on the supporting base, and a circuit breaker disposed on the hollow terminal to be tilted to be remote from the movable contactor, while two driving rods extend through the second insulator and are connected to the driving source to open and close the circuit disconnector through the operating mechanism and the circuit breaker through a linkage located within the hollow terminal. The power switch assembly may have further a porcelain clad lightning arrester substituted for the first insulator.
