What is a Relay Socket?

A relay socket is an electrical device which, when activated, allows the user to control and switch the current in a circuit. It works by either opening or closing two or more contacts type which are determined by the type of the relay socket used. Relay sockets are used as a general purpose switch in many applications and are commonly found in home and commercial zones.

Application Field of Relay Socket

Relay sockets are commonly used in industrial, commercial, and residential applications to control current flow in a circuit, either by opening or closing a single circuit or a series of circuits. In most cases, they are used to control the operation of equipment or machines in response to the input of an external source. In industrial applications, they are often used to control the motion of machines, and in commercial applications, they are used for switching electrical signals and controlling the power output of an appliance.

Working Principle of Relay Socket

The working principle of a relay socket hinges on a physical principle, wherein the directing current in magnetic coils causes a mechanical force which pulls on a small lever, to open or close a switch. As mentioned earlier, relay sockets have either one or two contacts. A single contact is usually used in applications such as a dry-contact relay which is usually used to activate high voltage equipment like pumps and compressors in industrial applications, while two contacts are usually used in applications such as an “on-off” switch to control an appliance’s power output. In order to open or close these contacts, the relays are usually triggered by the presence of an electromotive force (EMF), which may be an alternating or direct current, depending on the application.When an EMF is present, it activates the relay, causing the small lever to move and either open or close the contacts. As soon as the EMF is removed, the contacts either open or close again depending on their state prior to the EMF being applied. This cycle of activation and deactivation then repeats itself as long as the EMF is applied.

Conclusion

Relay sockets are widely used in many applications as a general-purpose switch for controlling currents in a circuit. They are generally triggered by an electromotive force and work on the principle that current in coils creates a mechanical force which is used to open or close contacts. This allows them to switch between open and closed states for the purpose of controlling the current flow in a circuit.
