📖 Product Description
The Micro Roller Lever Arm Limit Switch is a versatile miniature snap-action switch designed for detecting movement, position, or mechanical limits in machines and electronic systems. It features a spring-loaded metal lever with a roller at the end, allowing smooth and reliable triggering when touched by a moving object.
This switch includes three terminals: Common (COM), Normally Open (NO), and Normally Closed (NC). This allows it to be used in a variety of circuits depending on whether you want the switch to close or open when activated.
The compact size makes it ideal for use in 3D printers, CNC machines, robotic systems, automatic doors, industrial equipment, and DIY projects. It is commonly used as an end-stop or limit sensor to stop motors, detect positions, or trigger events.
The metal roller lever reduces friction and wear, making the switch more durable and suitable for repeated use. The switch can handle both low-voltage electronic circuits and higher-current control applications.
