Why should you use BS EN 3155‑070 - Electrical contacts used in elements of connection ?
Electrical contact is a switch that uses a secondary, low-voltage power source to complete or interrupt circuits that affect an electrical current. Electrical contacts, connectors, and connections are very important components in assuring performance and safety. 
BS EN 3155-070 provides guidance on the characteristics, dimensions, mass, markings of colour code, and the materials for surface treatments for the manufacturers and installers to ensure the quality and safety of male, type A, class S electrical contacts.
Making the proper connections to the electrical contacts will help keep the electricity flowing trouble-free. Electrical contact or connection failure can spell disaster for the facility or appliance’s operations.
BS EN 3155-070 also provides guidance for maintaining well-functioning electrical contacts, as it is also an important element to ensure the performance and safety of your electronic equipment and components.
