3D Printer Limit Switch
Limit Switch Module uses a small mustache switch to detect and send a signal when it is mechanically closed. Limit Switches are also known as endstops.
They are placed on the axes in 3D printers and CNC projects and are used to end the movement in order to understand when the axis reaches its end and to prevent damage to the system. It is compatible with most 3D printer control cards, especially Ramps.
