5Pcs Mini Micro Limit Switch

Meet the compact powerhouse for precision switching: the 5Pcs Mini Micro Limit Switch KW12 family designed for reliability in tight spaces. These switches deliver precise end-stop sensing with versatile SPDT (1NO+1NC+1COM) or SPST configurations and a robust 5A rating at 125V or 250V—making them ideal for DIY projects, small automation rigs, and compact machinery.

• What’s in the pack: five micro limit switches ready to deploy across multiple projects—great for multi-axis setups, dashboards, or ready-made replacement kits.
• Electrical versatility: choose SPDT (NO/NC with a common COM) or SPST (NO or NC) to match your schematic needs; 1COM, 1NO, and 1NC wiring provide flexible wiring options.
• Electrical rating: dependable 5A capability at 125V or 250V for signal and small-power control in a wide range of machines and electronics.
• Compact, durable design: slim 20x6x10 mm body crafted from plastic with metal contacts, engineered to withstand everyday use in hobbyist builds and light industrial tasks.
• Actuation options for tight spaces: 16 mm, 25 mm, and 55 mm arc lever styles, plus a roller lever variant for smooth, repeatable trips in constrained interiors.
• Easy mounting: two 2.35 mm holes with 9.5 mm spacing fit common chassis and panels without additional hardware.
• Certifications: CQC, CCC for reliable, standards-compliant performance.

Ideal applications: end-stop detection in compact 3D printers, mini CNC setups, and robotics projects; simple limit-switches for conveyor lines, door interlocks, and safety interlocks in small automation cells; perfect for prototype and educational kits where dependable, repeatable actuation matters.

Practical wiring tips:

• Use SPDT when you need a defined NO or NC path with COM as the common connection.
• Keep wiring neat and secure, and verify continuity with a multimeter during initial setup.
• Mount the switches using the two 2.35 mm holes, spaced 9.5 mm apart, to achieve stable alignment with moving parts.

With this 5-piece set, you gain a flexible, reliable switching solution that adapts to diverse projects—from hobby builds to light-duty automation. Whether you’re replacing worn end-stops or equipping a new compact machine, these KW12 micro limit switches deliver consistent actuation, clear electrical signals, and straightforward integration into your control circuits.
