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.
