Problems solved by technology

[0002] Existing power switches are always inseparable from metal solid-state switches, and it is always difficult to avoid the existence of arcing after the power switch is disconnected and closed. The arcing is easy to cause the surface oxidation of the solid metal switch blades, and the gas in some areas of the surface Changes in the appearance, surface deformation, and changes in the surface finish will lead to deterioration of the characteristics of the switching device, and the loss caused by the arcing of the switch that is often on-off is quite serious

Abstract

A power switch comprises a gate (1), a container (2), a support body (3), liquid metal (21), a first electrical node (IN+) and a second electrical node (IN-). The gate (1) is provided with a spherical contact; the spherical contact is provided with spherical cavities (10); the spherical centers of the spherical cavities (10) are within the surface of the spherical contact; and each spherical cavity (10) is provided with a circular opening (101) making the spherical cavity (10) and the outside communicated on the surface of the spherical contact; and the diameter of the circular openings (101) is smaller than that of the spherical cavities (10). A power circuit comprises the power switch. A power system comprises the power switch. The power switch of the invention is low in cost, flexible in application, long in service life, and stable and reliable.
