A miniature relay is a small electromagnetic switch that allows electrical circuits to be controlled by a low-power signal. When an electrical current passes through the coil of the relay, it generates a magnetic field, which in turn moves a mechanical arm to open or close contacts. This process enables the relay to control larger currents or different circuits using a low-power signal, making it essential for controlling devices and automating processes in various applications.

    The compact size of miniature relays makes them particularly useful in environments where space is limited. Despite their size, they offer high levels of efficiency, durability, and performance, which makes them ideal for a wide range of industries.
