DIY KD2 Buttons

Since the release of the new 3D printed MCP, lots of people have said that the Kd2 switches are too expensive to get hold of. Then Sammy asked if I could create a cheap replacement with readily available parts.

This is what I came up with, the switch utilises a standard push button and 5mm LED (any colour but green seems to be good for the MCP). If you would like this design please continue to read on and download the files as required. Enjoy and happy building.

Kind regards Karl.

As this is a very simple build, the build guide is here:

Insert the push button into the Base Cap, so that the button sits into the orifice.

Place the nut onto the protruding threads and tighten to secure in place.

Insert a 5mm LED into the orifice. I used green, but you can choose whatever colour you like.

Place the Button Cap into the orifice and push hard, an audible click will be heard. Make sure the legs of the LED protrude through the holes. Ensure you remember which is the anode and cathode.

Push the button cap assembly onto the button base. It should be a tight fit as the fingers grab onto the button head.

Place the button case over the top of the assembly and once again push hard so that the base clicks into the body. Ensure the legs or wires protrude through the unit at the rear. Insert into the MCP. I would use hot glue to secure them.
