EN 61020-1:2009

Electromechanical switches for use in electrical and electronic equipment - Part 1: Generic specification

IEC 61020-1:2009 provides consistency in detail specifications for electromechanical switches by specifying the terminology, symbols, test methods and other necessary information. Switches covered by this specification: - are devices which open, close, or change the connection of a circuit by the mechanical motion of conducting parts (contacts); - have a maximum rated voltage of 480 V; - have a maximum rated current of 63 A. This second edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: - The requirements of the IEC 60512 series of standards have been integrated. - Other necessary information concerning switches as specified in IEC 60512 have been implemented. The following items have been updated with respect to the first edition: - test methods were reviewed for detailed description; - the explanation for the test method of the operating force was rewritten in more detail; - the test voltage for measurement for contact bounce was reviewed; - the electrical endurance 'ON' duration in the duty cycle was harmonized with IEC 61058; - the requirements for fire hazards have been deleted; - testing methods of surface mounting switches based on the Japanese industrial standard were added.

Interrupteurs électromécaniques pour équipements électriques et électroniques - Partie 1: Spécification générique

La CEI 61020-1:2009 est destinée à assurer la cohérence des spécifications particulières applicables aux interrupteurs électromécaniques en spécifiant la terminologie, les symboles, les méthodes d'essai et autres informations nécessaires. Les interrupteurs relevant de la présente spécification: - sont des composants qui ouvrent, ferment ou commutent un circuit par le mouvement mécanique de leurs parties conductrices (contacts); - ont une tension assignée maximale de 480 V; - ont un courant assigné maximal de 63 A. Cette seconde édition constitue une révision technique et elle inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Les exigences de la série CEI 60512 ont été intégrées. - En particulier les informations nécessaires par rapport aux connecteurs tels que spécifiés dans la CEI 60512 ont été introduits dans cette norme. En outre, les points suivants ont été mis à jour par rapport à la première édition: - des méthodes d'essai pour une description détaillée ont été révisées; - l'explication pour la méthode d'essai des forces de fonctionnement a été réécrite plus en détails; - la tension de mesure des rebonds a été révisée; - la durée de l'endurance électrique 'marche' dans le cycle de service a été harmonisée avec la CEI 61058; - des exigences par rapport aux risques au feu ont été supprimées; - des méthodes d'essai des connecteurs montés en surface basées sur des normes industrielles japonaises ont été ajoutées.
