This document:
— establishes a working definition for switches and their constituent parts and identify the main types
— specifies the minimum requirements for the manufacture of the switches and/ or constituent parts
— specifies codes of practice for inspection and manufacturing tolerances of both full and half sets of switches and their constituent parts
— establishes the limits and scope of supply
— lists the methods by which switches and their parts should be identified and traced
— lists the different and varying ways by which switches can be described using the following parameters:
— geometry of the switches
— types of construction
— performance requirements
— design criteria
— tolerances and inspection.
