The 3-Pin Limit Switch is a compact mechanical switch designed to detect the presence, position, or movement of objects in electronic and automation systems. It features a lever actuator and three terminals for common, normally open (NO), and normally closed (NC) connections, making it suitable for robotics, Arduino projects, CNC machines, and industrial control applications.
Compact mechanical limit switch for position and motion detection.
Lever actuator responds to physical contact or movement.
Three terminals support NO and NC switching configurations.
Suitable for electronic circuits, automation systems, and robotics.
Easy to integrate into control panels and DIY projects.
