Introduction

This is a 3D printed switch for many uses, including controlling a computer when used with a switch adapter and screen scanning software.

There are three main sections and one optional section within this documentation:

• Mechanical - Covers 3D printing all the parts, as well as sourcing and installing fasteners.
• Electrical - Covers the custom circuit board and the components that go on it.
• Final Assembly - Explains how to fit all of the parts together into the completed switch.
• Custom Bases - Gives information on creating custom mounting bases so that the switch can be adapted and mounted as needed.

The electrical and mechanical sections must be completed before the final assembly can be attempted.
