KW11-3Z-3 Micro Limit Switch Series

The KW11-3Z Micro Limit Switch Series is a versatile and precise electromechanical switching solution widely used in automation, robotics, CNC machines, 3D printers, and general electronic control systems. Designed for hobbyists, engineers, and makers alike, these compact switches deliver reliable positional feedback and accurate switching action in a variety of applications.

This series is available in three variants to suit different mechanical configurations. The KW11-3Z-1 features no lever, ideal for direct plunger-style actuation. The KW11-3Z-2 comes with a short lever for applications requiring slightly extended reach. The KW11-3Z-3 includes a roller lever, providing smooth actuation with minimal friction, perfect for cam-driven or sliding mechanisms.

All three variants share a common PCB-friendly footprint with solder terminals, offering normally open (NO), normally closed (NC), and common (COM) connections for flexible circuit integration.
