IEC 60947-5-8:2020 is available as IEC 60947-5-8:2020 RLV<\/span> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60947-5-8:2020 specifies requirements for three-position enabling switches. These switches are used as components of enabling devices to provide signals that, – when activated, allow machine operation to be initiated by a separate start control, and – when de-activated, — initiate a stop function, and — prevent initiation of machine operation. This second edition cancels and replaces the first edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: – due to the increasing range of useful applications of three-position enabling switches, note of scope, operational characteristics and tests are reviewed; – figures for example of devices incorporating enabling switch are added in Annex A; – new Annex B for procedure to determine reliability data for the switch used in functional safety applications is added.<\/p>\n Low-voltage switchgear and controlgear – Control circuit devices and switching elements.
