Creality 3D Ender-2 Pro Limit switch

On a busy workbench, a Creality Ender-2 Pro owner is mid-print when the X-axis fails to home—the culprit is a worn-out limit switch. This replacement mechanical microswitch with a lever arm restores precise endstop detection for all three axes. It mounts with two screws and connects via a 3-pin JST-XH compatible header, making installation straightforward.

Key specifications

• Switch type: mechanical microswitch with lever actuator
• Contact configuration: SPDT, typically wired as normally closed (NC)
• Operating voltage: 5V DC max
• Current rating: 1A max
• Connector: 3-pin JST-XH compatible (on PCB, not switch)
• Compatibility: Creality Ender-2 Pro 3D printer (X, Y, Z axes)
• Material: ABS plastic body, metal lever
• Mounting: screw mount (2 holes)
• Operating temperature: -25°C to 80°C
• Electrical life: 1,000,000 cycles
• Mechanical life: 10,000,000 cycles
• Operating force: approx. 0.74N (75gf)
• Release force: approx. 0.1N (10gf)
• Pre-travel: 1.5mm
• Over-travel: 0.5mm
• Insulation resistance: >100MΩ at 500V DC

Why choose it

This limit switch is a direct replacement for the original part, ensuring consistent homing and preventing skipped steps. Its durable construction and long mechanical life mean fewer replacements over time. The lever arm provides reliable actuation even with slight misalignment, and the standard connector simplifies wiring.

Ideal use cases

• Replacing a faulty or worn limit switch on an Ender-2 Pro
• Keeping a spare for quick repairs during long print jobs
• Upgrading or maintaining the endstop system for reliable homing

Good to know

The switch is sold individually and does not include mounting screws or cables. Verify the connector orientation before installation. While designed for the Ender-2 Pro, it may fit other Creality printers with the same endstop design, but compatibility is not guaranteed.
