A General-purpose relay is a versatile and widely used electrical device that plays a crucial role in automating circuits, providing safety, and controlling various devices in different sectors. This simple yet powerful component has become an essential part of many electrical and electronic systems due to its ability to switch circuits on and off with ease. Whether in household appliances, industrial automation, or automotive systems, general-purpose relays offer an efficient and reliable solution for controlling electrical devices.

What is a General-purpose Relay? A general-purpose relay is an electromechanical device that opens or closes contacts in response to an electrical signal. It typically consists of a coil, an armature, a set of contacts, and a spring. When an electrical current flows through the coil, it generates a magnetic field that pulls the armature, causing the contacts to either close or open depending on the type of relay. These relays can handle both AC (alternating current) and DC (direct current) systems, making them adaptable to a wide range of applications. How Does a General-purpose Relay Work?
