Abstract: A submersible pump with UV sterilization device comprises a casing, at least one sterilization room and one water pump room being provided in the casing, a first end cap and a second end cap being separately fixed at the two ends of the casing, a front water inlet being provided at the first end cap, a back water inlet connected to the water inlet of the sterilization room being provided at the second end cap, and a reflection board being provided at the internal wall of the sterilization room; a water pump being fixed in the water pump room, a water outlet being fixed above the impeller room of the water pump, the impeller room being connected to the water outlets of the sterilization room, a cold cathode UV sterilization device being provided in the sterilization room, the sterilization device being connected to the output end of an inverter fixed in the casing.

Abstract: A hermetically sealed electrical switch assembly comprises a casing having an opening end. A cover is sealingly attached to said opening end of said casing for forming a primary volume hermetically sealed from external environment. Received in said primary volume are a switch means and a magnetic responsive means. A magnetic activating means is fitted at the upper surface of said cover for effecting the movement of said magnetic responsive means. The switch means comprises electrical contacts to change the conducting state of a power circuit with which said switch means is connected, a switching lever which can change its positions according to the conducting state of the power circuit. The magnetic responsive means couples with said switching lever for moving with it.

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.
