This is a 3D printer fabricated button-style adaptive switch. The design includes three main components, a circular base unit, a colored cap (the activation surface), and a ring that fits over the edges of the cap and screws on to the base. This model has a base that angles up at the back, so that the button activation surface is presented at a 35 degree angle. This position is easier for some people to see and activate. The cap is 2.5 inches in diameter and the entire switch is 1.5 inches tall at the back. 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.
