Roller Lever Endstop Switch Module — SPDT Microswitch, 3-Pin Header, 3D Printer Compatible

Roller Lever Endstop Switch Module — SPDT Microswitch, 3-Pin Header, 3D Printer Compatible

This roller lever endstop switch module combines a SPDT microswitch with a roller ball lever on a small PCB with a 3-pin header — the standard endstop switch format used in 3D printers (Prusa, Ender, Creality, and RepRap-based machines) and CNC machines. The roller ball provides smooth, low-friction actuation by the axis carriage, and the 3-pin header (GND, VCC, Signal) connects directly to the printer's control board endstop connector.

Module Specifications

• Switch Type: SPDT microswitch with roller ball lever
• Connector: 3-pin male header (GND, VCC, Signal)
• Output: Digital signal (NO or NC selectable by pin choice)
• Compatible: Prusa, Ender, Creality, RAMPS 1.4, SKR, and all RepRap-based 3D printers

3-Pin Header Connections

• GND: Ground
• VCC: 5V (for LED indicator if present)
• Signal (S): Switch output — connect to printer board endstop input

Typical Applications

• 3D printer endstops: X/Y/Z axis homing and travel limit switches
• CNC machine limits: Axis end-stop detection for CNC routers and mills
• Robot arm limits: Joint travel limit detection
• Position detection: Detect presence of moving parts in automated systems
