🔑 Key Features

✅ Mechanical Limit Switch – Reliable physical contact-based triggering. ✅ 3-Pin Connector (VCC, GND, Signal) – Plug-and-play with Creality motherboards. ✅ Normally Open (NO) Contact – Triggers when pressed (low signal). ✅ Long Lifespan – Rated for 100,000+ cycles. ✅ Easy Installation – Mounts with M3 screws (included). ✅ Compatible with Marlin & Klipper Firmware.

📊 Technical Specifications

• Type: Mechanical Microswitch (SPST – Normally Open).

• Operating Voltage: 5V (Standard for 3D printer logic).

• Current Rating: 0.1A @ 125V AC / 1A @ 30V DC.

• Trigger Force: ~160gf (light actuation).

• Connector: 3-Pin JST (or Dupont-style, depending on model).

• Mounting: M3 screw holes (fits Creality Ender-3 brackets).

• Dimensions: ~19mm × 10mm × 6mm (switch only).

🔧 Installation & Wiring

1. Mount the Switch: Secure to the X/Y/Z-axis endstop position using M3 screws.

2. Connect to Motherboard:

   • Signal (S) → Endstop pin on board (e.g., X-STOP).

   • VCC (+5V) → 5V power pin.

   • GND → Ground pin.

3. Test Homing: Use LCD menu → Auto Home to verify triggering.

⚠ Troubleshooting Tips:

• If the printer doesn’t stop, check for loose wiring or faulty switch.

• If false triggering, ensure the lever isn’t bent or obstructed.

🛠 Applications

• X/Y/Z-axis homing in Creality Ender-3, CR-10, and similar printers.

• Replacement for worn-out endstops (common after long-term use).

• DIY CNC machines & robotics (as a limit switch).

📦 Package Includes

• 1× Mechanical Endstop Switch (3-pin).

⚡ Why Choose This Endstop?

✔ OEM-Compatible – Direct replacement for Creality printers. ✔ Durable & Reliable – No false triggers from dust/vibrations (unlike optical sensors). ✔ Budget-Friendly – Cost-effective solution for 3D printer maintenance.
