The non-bending conductor with a flexible conductor is ger8 and 9 are also knotted together above and below the rails by bolts 12 and 13 from the Swiss patent 366 589, to keep U-shaped contact pieces. The supports 8 and 9 form together with the turns into which the contact arms are inserted from bolts 12 and 13 a rec'r.tick-shaped support frame. Between an inner and outer part of the men, on which the disc springs 10 and 11 are supported, U-shaped contact pieces are springs for generating

According to the invention, a further substantial increase is obtained for the embodiment of the power switch plug-in contacts described above. 1. Power plug contact for retractable line short-circuit current resistance and. Wins also power switch with a contact arm, which is built up from 5 an increased tolerance for the overlap of the two parallel rails, contact arm with the mating contact piece in which in turn at their facing operating position of the circuit breaker .
Inner surfaces at a certain distance from the free The invention thus relates to a high-voltage end of the contact arm projections for the installation of plug-in contact for withdrawable circuit breakers with on a counter-contact piece, because - io a KontaKarm, which is characterized by two parallel that is built between rails, which in turn, at their projections (4, S) and the free end of the facing inner surfaces in certain contact arms on the rails (1,2) a support frame (8,9, 12, surrounding the distance from the free end of the contact arm pre-contact arm) is fixed for engagement with a mating contact piece 13) having on the springs (10, 11 i reasonable). ₅ According to the invention, the new thing is that the rails (1, 2) are positioned between the projections and the free end of the L-circuit breaker against that of the contact arm on the rails, a fixed mating contact piece (3 ) is attached to the arm surrounding support frame, press on Jem. Springs are attached which hold the rails in the _{2.

For a further embodiment of the invention, the support frame of two parallel rails occupy a certain distance from each other by means of posts (12, 13) and beams that are spaced apart by bolts stand apart from one another between the girders and the rails. In addition, twin springs (10, 11) are arranged. see the girders and the rails disks
