Roller Lever Endstop Limit Switch Module

The Roller Lever Endstop Limit Switch Module is designed for use in 3D printers, CNC machines, and other automation projects where precise contact detection is required. Featuring a good-quality roller lever microswitch, this module provides smoother and more reliable travel limit detection compared to standard lever switches. When triggered, the onboard red LED lights up, offering clear visual feedback, while the output signal switches from HIGH to LOW.

With an 80cm 24AWG cable terminating in a standard Dupont female connector, this module is easy to integrate with microcontrollers or control boards. It is compatible with both 3.3V and 5V logic systems, making it versatile across a wide range of applications. Built with durability and practicality in mind, the Roller Lever Endstop Module is a dependable choice for 3D printers, robotics, automation systems, and DIY electronics projects. Featured By RoboticsBD.

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).

The module has several large mounting holes.

OUR EVALUATION RESULTS:

Build quality is good on these modules.

These modules are mainly designed to provide a logic input to a uC for it to take action on, but they can also be used to directly control a relay or similar device.  The LED has a 1K current limiting resistor, so voltage should be limited to 12V or so through the module.
