Sähkö- ja elektroniikkasymbolit
Sähkösymboli on pieni kuva, jota käytetään sähkö- tai elektroniikkalaitteen tai toiminnon kuvailuun. Niihin viitataan myös nimellä piiridiagrammisymbolit tai skeema-symbolit, koska niitä käytetään sähköisissä piirikaavioissa ja diagrammeissa.
Joitakin perussähkösymbolia ovat:
Johdot
Dioodi
Akut
Muuntimet
Kondensaattorit
Vastukset
Induktorit
Sulakkeet
Kytkimet
Bipolaarinen yhdistyskielektri
Elektromagneettiset releit
Maailmanlaajuisesti käytetään monia sähkö- ja piiridiagrammisymboleja. Vaikka ne ovat pääasiassa standardoituja (eli samat elektronisisymbolit käytetään eri maissa), löydät vieläkin joitakin kansainvälisiä eroja.
Alla on taulukko yleisimmistä sähkösymboleista, jotka käytetään
