Introduction
A PCB electromagnetic relay is a widely used electrical component that plays a vital role in switching circuits in various applications. Its compact size and effective performance make it an essential component for controlling high-power circuits with low-power signals. This article delves into the working principle, construction, and applications of the PCB electromagnetic relay, offering an insight into why it is an indispensable element in modern electronics.
What is a PCB Electromagnetic Relay?
A PCB electromagnetic relay is a type of relay that is mounted directly onto a printed circuit board (PCB) and operates using an electromagnet to switch electrical contacts. It is a versatile electromechanical device that allows a low-voltage electrical signal to control the switching of a higher-voltage electrical circuit. This functionality is crucial in many electronic systems, as it isolates low-power control circuits from high-power circuits, ensuring both safety and efficiency.
