A radio-frequency power switch consists of at least two annular contact parts having spring contact rings which are inserted into the ring hole and are mounted in an insulating manner at a distance from one another, with their ring holes axially aligned, and of a cylindrical contact piston which fits into the spring contact ring in a sliding manner and can be displaced axially between the two contact parts via an operating rod made of insulating material and an axial drive which interacts with it.
