DESCRIPTION

This lever endstop switch module is designed for use as an endstop for 3D printers but it can be used for other contact detection applications as well.

PACKAGE INCLUDES:
  • Lever Endstop Switch Module
  • Cable
KEY FEATURES OF ROLLER LEVER ENDSTOP SWITCH MODULE:
  • Good quality roller lever microswitch
  • Use as travel limit switch on 3D printers or other contract detection applications
  • long 26AWG cable
  • Red LED illuminates when switch is activated
  • 3.3 and 5V logic compatible

The module was designed to detect travel limits for 3D printers, but they will work for many contact detection applications as well.

This module mounts a microswitch with a roller lever that rolls across the contact surface rather than scraping it as a normal lever can.

The output is normally pulled HIGH.  When the beam is broken, the output is pulled LOW and a red LED on the module illuminates.

The module uses a 4-pin 2.54mm JST style connector.  The other end of the cable terminates in a 3-pin female Dupont style connector that is compatible with a standard 2.54mm male header.

Module Connections

Note that the board is not labeled, but you can go by the cable wire colors to make connections.

1×4 Connector

  • Red Wire = VCC (3.3 or 5V to match the uC.)
  • Black Wire = Ground which should be common with the uC.
  • N/C = Not connected, but is grounded on module side
  • Green Wire = Signal output of the module.  This pin is normally pulled HIGH via a 10K pull-up resistor.  When the switch is depressed, the output goes LOW (shorted to ground).
