Abstract

One switching arm of the rotary isolator carries at its free end the countercontact member (81, 82) produced of flat sections (41, 42). The other switching arm is formed of four flat sections (51, 52, 53, 54) which are bent outwards at the end of the switching arm and are used as elastic contact fingers. At the sides of the mutually oppositely arranged contact fingers (51, 53 and 52, 54), which face away from one another, rigid links (9) are attached which are pulled against one another by means of a spring (11) generating the contact pressure. A tube (16) surrounding the spring (11) provides for the spacing between the contact fingers when the isolator is open. Since the links (9) rest on the contact fingers on the one hand in the active area of a spacer (10) located between the contact fingers and, on the other hand, in the contact area of the countercontact member (81, 82), the contact fingers are not stressed for bending in the contact area of the countercontact member (81, 82). A higher operating temperature is permitted for this contact arrangement than for one with contact fingers stressed for bending in the contact area. The spring-loaded links (9) also act in an oscillation-damping manner in the case of a short circuit current. When the contact members are severely iced, the contact fingers can be spread widely without damage.
