Electromechanical Relays

Electromechanical relays serve as versatile switching devices widely utilized in control circuits. They make it possible to switch electrical contacts on or off using contact positions that can be changed with a magnet. When this type of relay is powered, an electromagnet is energized; the current flowing through the coil generates a magnetic field that pulls the movable armature to the contacts, changing the contact position, enabling current to flow in the circuit, or disabling it. And doing all this by pulling a little armature with a whole lot of magnetic force is, as the saying goes, relaying on the (low-power) magnetism to achieve a (high-power) result.

Electromechanical relays are still highly regarded for all of the reasons that have made them longstanding devices. Their simplicity, cost-effectiveness, and the fact that they can handle surge currents and transient conditions make them still quite useful. Although solid-state relays are more and more being adopted in some applications because of their speed and durability, electromechanical relays are still a very common choice in situations where you want the kind of devices that provide mechanical, switching, and feedback operations.
