The invention relates to a knob connection for a multipolar switching device that is composed of single-pole switching devices, the single-polar switching devices of which have thermoplastic operating knobs, arranged juxtaposed and pivoting around a common axis, and connected by means of a rigid grip strip covering the individual operating knobs. The operating knobs (1) have, on the narrow side facing upwards, a slit-like recess (1.3) closed on both front sides (1.4) and running in axial direction. The recess has undercuts (1.6), facing both side faces, in a plane perpendicular to the axis direction (2.1'). The grip strip (3), which is also made of thermoplast, has peg-shaped protruding elements (3.1), across the width of the single-pole switching devices and corresponding to their number, which, with serrated projections (3.2) adapted to the undercuts (1.6), can be later, elastically, as well as captively locked twist-proof into the recesses (1.3), while lengthwise along the grip strip (3), between the protruding elements (3.1) and the recesses (1.3), there is sufficient play to compensate for tolerances and material contraction.

Prikazana je povezava s prečnim drogom za večpolno stikalno pripravo, ki je sestavljena iz enopolnih stikalnih priprav in katere druga poleg druge nameščene enopolne stikalne priprave izkazujejo okoli skupne osi zasučne in iz termoplasta izdelane posluževalne prečne drogove, ki so povezani s pomočjo toge prijemalne letve, ki sega preko posameznih posluževalnih prečnih drogov, pri čemer so posluževalni prečni drogovi (1) na svoji navzgor segajoči ozki strani opremljeni z režasto odprtino (1.3), ki poteka v osni smeri in je na obeh čelnih stranicah (1.4) zaprta in ki s svoje strani proti obema stranskima ploskvama v ravnini pravokotno na osno smer (2.1') izkazuje spodreze (1.6), in pri čemer prav tako iz termoplasta izdelana prijemalna letev (3) v delitvi enopolnih stikalnih priprav kot tudi ustrezno njihovemu številu izkazuje čepasto štrleče nastavke (3.1), ki se naknadno elastično kot tudi neizgubljivo in zasučno varno zaskočijo v odprtine (1.3) z v obliki žaginega zoba oblikovanimi izrastki (3.2), ki so prilagojeni spodrezom (1.6), medtem ko je v vzdolžni smeri držalne letve (3) med nastavki (3.1) in odprtinami (1.3) prisotno dovolj zraka za izravnavo toleranc in materialne obrabe.ŕ
