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.
