Abstract

Et symmetriledd som er meget plassbesparende og som kan produseres med lite oppbud, består av fire sammenkoblede, plane ledninger (1, 2, 3, 4). En ende av den første ledning (1) er utformet som en første symmetrisk tilkoblingsklemme (5). Den annen ende av denne første ledning (1) er forbundet med den ende av den andre naboledning (2) som ligger ved siden av. Den ende av den andre ledning (2) som er forbundet med den første ledning (1) danner en usymmetrisk tilkoblingsklemme (7), mens den annen ende av den andre ledning (2) står i kontakt med jord (8). Den ende av den tredje ledning (3) som er nabo til den andre ledning (2) og som ligger ved siden av den usymmetriske tilkoblingsklemme (7), står i forbindelse med jord (10), mens den annen ende tjener som den andre symmetriske tilkoblingsklemme (9). Den ende av den fjerde ledning (4) som ligger ved siden av den andre symmetriske tilkoblingsklemme (9), står i forbindelse med jord (11), mens den annen ende er forbundet med den ende av den andre ledning (2) som danner den usymmetriske tilkoblingsklemme (7).
