    摘要： An electric switch having an axially movable switching contact and a resilient annular fixed contact. The fixed contact is in permanent contact with said switching contact and consists of a zigzag folded metal strip surrounded and supported by an annular holder. The metal strip is bent in the shape of a ring which snugly encloses the switching contact and is constituted by a circular series of pairs of contact lips.

    摘要： A solid dielectric deadfront electrical switch assembly having a switch contact assembly. The switch contact assembly can include an upper insulative diaphragm, a male pin contact having an insulating tip and an isolating sleeve, a primary contact, a lower insulative diaphragm, and a female socket contact. The upper insulative diaphragm, isolating sleeve, and insulating tip can assist in electrically isolating the male contact pin when the electrical switch assembly is in an open condition. Further, the upper insulative diaphragm can be separated from the female socket contact, and/or a female-contact insulating sleeve, by a gap chamber that utilizes air as an insulator. The lower insulative diaphragm can be configured to engage a drive rod that is used to axially displace the male pin contact between open and closed positions in a manner that may prevent arcing between the switch contact assembly and a base plate of a switchgear.
