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.
