The PCB limit switch (Micro Switch) is a small but highly useful mechanical switch used for position control or motion limit detection in electronic circuits and devices. It is activated with minimal mechanical pressure, providing immediate and reliable response. It is widely used in printers, CNC machines, robots, 3D printers, and other automation applications. It stands out for its compact design, long-lasting durability, and stable operation, making it an essential component for precise detection and equipment protection.
