Small Limit Switch

Product Overview

The Small Limit Switch is a compact, high-precision mechanical switch designed for reliable position detection and end-stop applications. Featuring a durable lever actuator and a snap-action mechanism, this switch delivers fast, repeatable switching ideal for automation, CNC machines, robotics, 3D printers, and hobby electronics.

Why Choose This Small Limit Switch

• Compact form factor makes it easy to integrate into tight spaces and small enclosures.
• Snap-action mechanism provides quick and reliable transitions for accurate limit detection.
• Lever actuator offers precise actuation and long-term durability under repeated cycles.
• Versatile 3-pin wiring (COM, NO, NC) supports both normally open and normally closed configurations.

Key Features

• Compact and lightweight design for space-constrained installations
• Snap-action mechanism for rapid response and consistent actuation
• Durable lever actuator built for repeated mechanical cycling
• 3-pin terminals: COM, NO, NC for flexible wiring options
• Easy installation with screw holes for secure mounting
• Suitable for low-voltage, low-current circuits in control and sensing roles

Specifications

• Switch Type: Mechanical limit switch
• Terminals: 3-pin (COM, NO, NC)
• Actuator: Lever type
• Mounting: Screw holes for easy fixing
• Size: Small and compact
• Rated Voltage/Current: Typically 250V AC / 5A (varies by model)

Wiring and Mounting Guidelines

• Identify COM, NO, and NC pins before wiring. COM to supply, NO for circuit that closes on actuation, NC for circuit that opens on actuation.
• Use appropriate gauge wire and secure terminals to prevent intermittent connections.
• Mount the switch using the provided screw holes. Ensure the lever and actuator path are unobstructed for reliable operation.
• For safety interlocks and motor end-stops, confirm wiring and test switching action at low power before full operation.

Typical Applications

• End-stops and homing switches for CNC machines and 3D printers
• Limit detection in robotic arms and articulated mechanisms
• Safety interlocks and motor cutoff switches
• Position sensing in automation systems and DIY electronics projects

Installation Tips

• Mount the switch on a stable surface to avoid vibration-induced false triggers.
• Adjust lever contact position to ensure consistent actuation and avoid mechanical over-travel.
• For long-term reliability, keep the contact area free of debris and verify operation periodically.
