An electromechanical relay (EMR) is a crucial electrical device that plays a significant role in a wide range of applications, from simple home appliances to complex industrial machinery. At its core, an electromechanical relay is a switch that is activated by an electrical current to open or close a circuit. This fundamental component operates by using an electromagnet to mechanically actuate a set of contacts, allowing or interrupting the flow of electrical current.
How an Electromechanical Relay Works The operation of an electromechanical relay is relatively straightforward. When an electrical current passes through the coil of the relay, it generates a magnetic field. This magnetic field causes an armature (a movable iron piece) to move, which in turn either opens or closes the relay’s contacts. These contacts are responsible for either completing or breaking the circuit, thus controlling the flow of electricity to other parts of the system. The relay typically consists of several key components: Electromagnet Coil: The coil generates the magnetic field when electrical current flows through it.
