Static contact assembly and isolating switch

The invention belongs to the technical field of high-voltage switches, and particularly relates to a static contact assembly and an isolating switch. The static contact assembly comprises a contact seat and conductive contact fingers which are arranged on the contact seat and used for being in conductive contact with a moving contact assembly of the disconnecting switch, the conductive contact fingers comprise a main contact finger, an auxiliary contact finger and arc striking contact fingers which are symmetrically arranged on the contact seat and used for allowing a moving contact to be inserted into one end, and arc striking blocks are arranged on the arc striking contact fingers. The structure of the static contact assembly in the prior art is simplified, and the compact structural design is easy to realize; in the bus conversion operation process, before the conductive contact fingers of the moving contact and the static contact are separated, current is passed through the main contact finger; after the
