Switches for appliances - Part 1: General requirements
IEC 61058-1:2016 applies to switches for appliances. The switches are intended to control electrical appliances and other equipment for household or similar purposes with a rated voltage not exceeding 480 V and a rated current not exceeding 63 A. This fourth edition cancels and replaces the third edition published in 2000, Amendment 1:2001 and Amendment 2:2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) requirements for mechanical switches are now given in IEC 61058-1-1;
b) requirements for electronic switches are now given in IEC 61058-1-2.
Interrupteurs pour appareils - Partie 1: Exigences générales
L'IEC 61058-1:2016 s'applique d'une manière générale aux interrupteurs pour appareils. Les interrupteurs permettent de commander des appareils électriques et autres matériels pour usage domestique et analogue dont la tension assignée ne dépasse pas 480 V et le courant assigné ne dépasse pas 63 A. Cette quatrième édition annule et remplace la troisième édition parue en 2000, l'amendement 1:2001 et l'amendement 2:2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) les exigences relatives aux constructions d'interrupteurs mécaniques sont maintenant incluses dans l'IEC 61058-1-1;
b) les exigences relatives aux constructions d'interrupteurs électroniques sont maintenant incluses dans l'IEC 61058-1-2.
