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.
