Contact switches used in manufacturing lines and automation equipment to detect the position and operating range of mechanical parts and send signals to control systems. When the actuator is physically pressed, the contacts switch to output ON/OFF signals. Used for industrial robot arm position detection, conveyor product position confirmation, press machine safety devices, and automatic assembly equipment part positioning. We handle diverse products according to applications including IP67 waterproof and dustproof specifications, high-temperature environment compatible products, and compact thin-type models. Unlike proximity sensors and photoelectric sensors, these switches feature reliable detection through physical contact and stable operation even in manufacturing environments with high vibration and dust.
