Relay Contact

A relay contact is a switch operated by an electromagnet in a relay, used to open or close circuits electromechanically or electronically.

Control Relay Contacts

Components in a relay used to open or close an electrical circuit, thereby controlling the flow of electricity based on a control signal.

Contactors

Electrically controlled switches used for switching an electrical power circuit, similar to a relay but with higher current ratings.
