This part of IEC 60947 specifies requirements for three-position enabling switches. These switches are used as components of enabling devices described in 10.9 of IEC 60204-1 to provide signals that, when activated, allow machine operation to be initiated by a separate start control and when de-activated, initiate a Stopp function, and prevent initiation of machine operation.
