Definitions:

Permanent Contact

A type of electrical contact that remains closed to ensure a constant flow of electricity, typically used in switches or relays.

Normally Open

A term describing an electrical switch or relay contact that is open (not conducting) when in its default state, closing only in response to a control action.

Normally Closed

A term used to describe a switch or circuit condition where the default state is closed, allowing current to flow unless actuated to open.

Normally Closed

Refers to an electrical switch or relay configuration where the contacts are in a closed position, allowing current flow, when no actuating force is applied.
