Looking for a way to connect your Limit switches to your controller board? Here's a solution for you.
These jumpers consist of 3x 70cm long wires with a 3 pole female DuPont type connector on each end.
Simply cut them to the desired length and solder them onto the opto switch or microswitch.
3 pin cables are required for elctronic limit switches where +5V and Ground are required as well as the wire carrying the signal back to the controller.
For a simple mechanical microswitch only 2 wires are needed.
