Mechanical Endstop Limit Switch Module – 3D Printer RAMPS 1.4
Mechanical Endstop Limit Switch Module – 3D Printer RAMPS 1.4
Mechanical Endstop Limit Switch Module for 3D Printers & CNC Machines
Upgrade your 3D printer or CNC build with the Dolyper Mechanical Endstop Limit Switch Module — a reliable, easy-to-install touch switch kit designed for RepRap printers, RAMPS 1.4 boards, Mega2560 control boards, and other popular RepRap-compatible electronics. Available in convenient 3-pack, 6-pack, or 9-pack bundles to suit your project needs.
Key Features
- Wide Compatibility: Fully supported by RepRap electronics, RAMPS 1.4, Mega2560, and other mainstream RepRap control boards.
- Premium 22AWG Wiring: Thick copper-core wire rated up to 2A current and 300V voltage — far superior to standard thin copper connections.
- High-Temperature Insulation: The insulating layer withstands temperatures up to 80°C, ensuring stable performance even in demanding environments.
- Generous Cable Length: Each module comes with a 70 cm (approx. 27.5 in) cable for flexible routing inside your printer or CNC enclosure.
- Compact & Precise: Measures just 32 × 10 mm — a slim, universal form factor that fits most standard mounting positions.
- No Assembly Required: Plug-and-play design; connects straight to your control board with no soldering needed.
- Universal Mounting: Commonly used model with strong universality across DIY and commercial 3D printer builds.
Wiring / Connection Guide
- Red Wire → VCC (RAMPS "+")
- Black Wire → GND (RAMPS "−")
- Green Wire → SIGNAL (RAMPS "S")
Note: A properly configured 3D printer or CNC system typically requires a minimum of three mechanical endstop switches (one per axis).

Frequently Asked Questions
Q: Are these mechanical endstop limit switches compatible with RAMPS 1.4 and Mega2560 boards?
A: Yes! These mechanical endstop limit switch modules are fully compatible with RAMPS 1.4, Mega2560 control boards, and a wide range of other RepRap-based 3D printer and CNC electronics. The three-wire (VCC, GND, SIGNAL) connector plugs directly into the standard endstop header on your control board.
Q: How many endstop switches do I need for my 3D printer?
A: A standard Cartesian 3D printer requires a minimum of three mechanical endstop switches — one for each axis (X, Y, and Z). Selecting the 3-pack covers a single printer, while the 6-pack or 9-pack is ideal for multi-printer setups or as backup spares for your workshop.
Q: What is the cable length on each module?
A: Each mechanical endstop limit switch module includes a 70 cm (approximately 27.5 inches) cable, providing ample length for flexible routing within most 3D printer frames and CNC enclosures.
Q: Do I need to solder anything to install these limit switches?
A: No soldering is required. These modules come pre-assembled and pre-wired with a standard 3-pin connector, making installation straightforward — simply plug into your RAMPS or compatible control board's endstop connector.
