This is a 3D printer fabricated button-style adaptive switch. The design includes three main components, a circular base unit, a cap (the activation surface), and a ring that fits over the edges of the cap and screws on to the base. The cap is 1 inch in diameter and the entire switch is 1/2 inches tall. It utilizes the industry standard 3.5-mm mono jack attached to a 5-foot cable. A simple press anywhere on the top will provide a switch closure with a solid audible 'click' feedback. **$20 replacement cost.
