This document relates to electromechanical switches intended for use in electrical and electronic appliances. Switches covered by this document: a) are devices which open, close, or change the connection of a circuit by the mechanical motion of conducting parts (contacts); b) have a maximum rated voltage of 480 V; c) have a maximum rated current of 63 A. This third edition cancels and replaces the second edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition: a) In accordance with the ISO/IEC Directives, Part 2:2016, Clause 2 General has been replaced by two new clauses: Clause 2 Normative references and Clause 3 Terms, definitions, units and symbols. 2.4 Preferred values and 2.5 Marking have been moved to Clauses 5 and 6. In addition, 6.2 Markings on packaging has been added. b) Clause 3 Quality assurance procedures and Annex A have been deleted. c) 4.3.6.3 Returning force has been added. d) 4.3.6.4 Travel (movement of the actuator) has been added. e) 4.12 Environmental testing: 4.12.1.3 and 4.12.1.5 have been renumbered 4.12.2 and 4.12.3, respectively. 4.12.1.4 and 4.12.1.7 have been integrated in 4.12.5. 4.12.10 Salt mist has been added. f) Following publication of IEC 61058-1-1:2016, some cross-references to IEC 61058-1 have been updated. g) The following items have been updated with respect to the second edition. - Tables and figures: Tables 1 and 3 have been deleted, Table 4 has been renumbered to Table 10. New Tables 2, 3, 4, 5, 6, 7, 8 and 9 have been added. Figure 1 has been renumbered to Figure 3, Figure 2 renumbered to Figure 4, Figure 3 renumbered to Figure 9 and Figure 4 renumbered to Figure 12. Added new Figures 1, 2, 5, 6, 7, 8, 10 and 11 have been added. - Specific words and common names have been unified.
