Detailed rules for control switches based on the general rules of BS 5472:1977 [EN 50005].

This standard applies to control switches according to IEC Standard 337-1, with two definite positions (such as push-buttons, limit-switches and similar devices), irrespective of their construction, having terminal marking in accordance with the corresponding marking of contactor relays designated by the distinctive letter E (see EN 50011).

The use of this standard is recommended where terminal marking is a requirement of the relevant standard for control switches, or is usual practice.
