NOTE 1 This standard does not apply to electromechanical control circuit devices as described in IEC 60947-5-1 .
NOTE 2 IEC 61 81 0-2-1 provides guidelines for the assignment of reliability values.
NOTE 3 Contacts that are not mechanically linked (forcibly guided) are not considered in this standard.
