Mechanical Endstop Module V1.2 with Cable Endstop Limit Switch Module for CNC 3D Printer Ramps 1.4 Laser Engraver End stop

3D printer limit switch uses a lever to detect when it is energized. When this 3d printer endstop activates, it pulls the signal to LOW. There is also an LED to light up when the switch is activated. 3D printer ramps 1.4 endstop wiring uses a standard 4 pin 100″ pitch header and accepts a standard, old-style CD-ROM audio connector cable. The mechanical end stop 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 interruption, 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 module when it moves against it.
