The scope of this European Standard is:
- establish a working definition for switches and their constituent parts and identify the main types;
- specify the minimum requirements for the manufacture of the switches and/or constituent parts;
- specify codes of practice for inspection and tolerances of both full and half sets of switches and their constituent parts;
- establish the limits and scope of supply;
- list the methods by which switches and their parts should be identified and traced;
- list 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.
