Creality Y-axis Limit Switch HI model 2104010154 for 3D printers

The Creality Y-axis Limit Switch HI model is a mechanical endstop designed to detect the Y-axis home position in Creality and compatible 3D printers. It provides a physical contact point for printer firmware to register the carriage or bed position, enabling accurate homing, position safety and prevention of axis overrun. This spare part is typically used as a direct replacement for worn or faulty Y-axis endstops on control boards and motion assemblies.

Advantages

This mechanical limit switch offers a simple and robust solution for Y-axis position detection. Its mechanical actuation requires no calibration in firmware beyond standard endstop settings, and it is compatible with commonly used Creality wiring and mounting points. The component is compact, reliable under repeated cycles, and serves as an economical spare part to restore correct homing behavior and improve motion safety in printers.

Suitable for

• Repairing or replacing a faulty Y-axis endstop in Creality and compatible 3D printers
• Restoring accurate homing and preventing bed or carriage overrun
• Use as a spare part for maintenance and long-term reliability of motion systems

When it may not be suitable

This mechanical switch is not suitable where non-contact or optical endstops are explicitly required for a specific upgrade, such as inductive or optical sensors used for silent or high-speed applications. It may also be incompatible with printer designs that use integrated or custom endstop assemblies with different mounting geometries or connector types.

Key specifications

• Type: Mechanical lever-actuated limit (endstop) switch
• Intended axis: Y-axis position detection
• Function: Normally closed or normally open contact depending on wiring (standard mechanical endstop behavior)
• Mounting: Compact form factor compatible with Creality-style endstop mounts (check printer mounting points)
• Durability: Designed for repeated mechanical actuation cycles typical in 3D printer use

How to use

Mount the switch in the Y-axis endstop location on the printer frame or carriage using the existing mounting holes or bracket. Connect the switch wires to the printer control board endstop pins, observing the board's required wiring configuration and polarity for normally open or normally closed operation. After installation, test the endstop in the printer's control interface or firmware by manually triggering the switch and verifying the printer recognizes the home signal. Adjust the lever orientation and mounting position if necessary to ensure reliable contact at the intended home location.

What to consider before purchase

• Confirm compatibility with your printer model and the physical mounting points for the Y-axis endstop
• Ensure the connector and wire length match your control board or plan to rewire/extend as needed
• Decide if a mechanical switch meets your needs or if a non-contact sensor would be preferable for your setup

Usage recommendations

For reliable operation, position the lever so the switch is consistently actuated at the exact home location; check and tighten mounting hardware periodically and avoid contaminating the switch mechanism with lubricant or debris. Verify endstop behavior in firmware after installation and perform a controlled homing move to confirm correct operation before printing.
