Mechanical Limit Switch Module

From the shop's description

Mechanical Limit Switch Module is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. 3D printer Endstop mechanical limit switch RAMPS 1.4 Description: The mechanical endstop is a simple solution to a simple problem. We want to be able to detect when an X/Y/Z stage has reached its minimum or maximum. Instead of messing with flags or complicated light beam interruptors, we use a mechanical switch. If we place the switch in the path of the stage, then the stage itself will simply close the switch when it moves against it. Other than properly positioning the switch, we do not need to modify the stage at all. Board Size: Approx. 39 x 16 x 7mm Cable Length: 65 cm Connection: Red Wire: VCC (ramps of +) Black Wire: GND (ramps of -) Green Wire: SIGNAL (ramps in s) It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
