Frequently Asked Questions

Q: Are these limit switch endstops compatible with RAMPS 1.4 boards?

A: Yes, these mechanical limit switch endstops are fully compatible with RAMPS 1.4 control boards and plug directly into the endstop headers — no additional wiring or adapters needed.

Q: Do I need any special tools or soldering skills to install these limit switches?

A: No special tools or soldering are required. Each switch is pre-assembled and designed for plug-and-play installation on most popular 3D printer platforms including Prusa I3, Delta, Kossel, and Makerbot.

Q: Why do I need 10 switches — how many does a typical 3D printer use?

A: A standard Cartesian 3D printer (such as the Prusa I3) typically uses 3 endstop switches — one for each axis (X, Y, Z). Delta printers like the Kossel use 3 as well (one per tower). This 10-pack gives you enough to outfit multiple printers or keep replacement switches on hand for future DIY projects.

Q: Are these normally open (NO) or normally closed (NC) switches?

A: These are normally open (NO) mechanical limit switches. When the print head or carriage makes contact, the circuit closes, sending a signal to the 3D printer board to stop axis movement — ensuring accurate and repeatable homing.
