A Reed relay, otherwise known as an “electromagnetic switch”, is a type of electronic switching device that is highly efficient and reliable. Although the switch is not as compact as some other switching solutions, it still offers a large number of advantages over competing switches. In this article, we’ll take a closer look at Reed relays, their fields of application, and their working principles.

Unlike most other types of relays, a Reed relay does not use a mechanical actuator to perform switching. Instead, it uses a special type of magnetically-sensitive contact that is made from an alloy of two or more metals. The contacts, also known as “reed contacts”, are encased in a vacuum-sealed envelope that protects them from external influences such as dust, moisture, and heat. The contacts are sealed in such a way that only a magnetic field can move them, thus enabling the switch to be actuated without any physical means.

The most common application of a Reed relay is in the control of electrical circuits. Its compact size and reliable operation make it ideal for use in compartments where space is at a premium. In addition, its low-power consumption makes it a highly efficient solution for controlling electrical circuits without the risk of overheating or burning out the components.

In addition to being used as an electrical switch, Reed relays can also be used in a variety of other applications. For example, they can be used to control lighting, as well as alarms and other security systems. They can also be used in various types of medical devices, such as oximeters and pacemakers. In addition, they are often used in automated test equipment, as well as industrial automation.

The working principle of a Reed relay is simple. When a current is applied to the control terminal, a permanent magnet is activated and causes the reed contacts to close. This creates a magnetic field that moves the contacts away from each other, thereby breaking the circuit. When the current is removed from the control terminal, the magnet is deactivated and the contacts move back to their original position, thus completing the circuit.

In conclusion, Reed relays are highly reliable and efficient switching solutions that can be used in a wide variety of applications. From providing reliable control of electrical circuits to being used in automated test equipment, medical devices, lighting control, and security systems, Reed relays offer a number of advantages over competing switches. Furthermore, their straightforward working principle makes them easy to use, making them an ideal solution for many applications.
