- Definição1
- An electrically operated switch. One switch contact is mounted on a movable steel arm, the armature, which is held away from the fixed contact by a spring. When current flows through the electromagnetic coil of the relay, it pulls the armature down and causes the movable contact to press tightly against the fixed contact, closing the switch. Relays are used to remotely control a large amount of current by using a small amount of control current flowing through the relay coil. Relays are being replaced in many types of electrical equipment with solid-state components that do the same job, but have no moving parts.
