摘要（英）：

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.
