Zusammenfassung:The switch arrangement (10) has three identical insulating support frames (12, 12'), in the tubular insulating housings (16) of which a vacuum interrupter (28) is arranged in each case. Parallel insulating wall elements (18), on which bearing elements (26) for drive parts of the spring energy drive (20) are formed, protrude from the insulating housings (16). The output shaft (22) of the spring energy drive (20) is mounted on all insulating wall elements (18), while the remaining drive parts are arranged on the insulating wall elements (18) of the middle insulating support frame (12').
