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,
\n– when activated, allow machine operation to be initiated by a separate start control, and
\n– when de-activated,
\n— initiate a stop function, and
\n— prevent initiation of machine operation.
\nThis 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:
\n– due to the increasing range of useful applications of three-position enabling switches, note of scope, operational characteristics and tests are reviewed;
\n– figures for example of devices incorporating enabling switch are added in Annex A;
\n– new Annex B for procedure to determine reliability data for the switch used in functional safety applications is added.<\/p>\n","protected":false},"excerpt":{"rendered":"
