Relay sockets are a type of potential accessory employed by using electromechanical switches. Relay sockets create a component of a circuit and are made available to mount relays. They ensure the electrical interface between the relay and the circuit. A relay is an important switch that is operated electrically instead of mechanically. It is typically powered by an electromagnet. These relays are plugged into the socket’s female mount, and the socket is wired to the wider circuit.
Specifications
When choosing relay sockets, additional factors to take into account include electrical rating, insulation resistance, dielectric strength, and temperature range. Some items are built for demanding uses, are shatterproof, or are flame retardant. Others include on/off switches that are mechanical or electronic, including:
- Single-pole (SP) sockets are employed with relays that monitor a single line with each throw.
- Double-pole (DP) components are used with relays that automate two lines. Commonly, the first line is warm, and the second line is neutral.
- Triple-pole (TP) sockets make use of three pairs of connections.
- Four-pole devices (4P) allow four pairs of connections.
Mounting Styles
There are several mounting styles for relay sockets.
- Through-hole technology (THT) mounts devices on a printed circuit board (PCB) by putting equipment leads via holes in the board and finally soldering the leads in place on the alternate side of the board.
- Surface mount technology (SMT) integrates components by soldering equipment leads or endpoints to the top area of the board. Typically, the printed circuit board pad is layered with a paste-like formulation of solder and flux.
What are Relay Sockets Used for?
Relay sockets interface relays to electrical contacts. Thus, they facilitate the installation or exchange of relays in automotive devices, long presses, motors, and other industrial devices.
Types of the Relay Socket
Depending on the kind of relay being utilized, relay sockets vary. Relays come in a variety of forms, such as solid-state, general-purpose, and latching or non-latching. Additionally, there are many mounting techniques for relay sockets, such as panel mounts and flange mounts, and the mounting technique has an impact on the design of the relay socket you require.
