3 Terms and Definitions

3.1 General terms

3.1.1 electrical contacts

3.1.1.1 Contact

A plurality of conductive elements, to establish the continuity of the circuit to each other upon contact, and, due to their relative movement in operation, the disconnect

Or a closed circuit; or under sometimes hinged or sliding element, to maintain the continuity of the circuit.

3.1.1.2 Mechanical switching device main circuit contacts

In the on-state current carrying the main circuit.

3.1.1.3 It aims on which arcing contacts

Arcing contacts can cater main contact, it can also be designed as a single contact, in order to keep carrying the operating current

Contacts from arc erosion.

3.1.1.4 Mechanical switching auxiliary circuit contacts

With the main contacts simultaneously.

3.1.1.5

It is a relative movement between the contacts and the contacts along a direction parallel to the contact surface of the slide.

3.1.1.6

The relative motion between the contacts is a contact along the surface normal direction of the contact.
