This is a 3D printer fabricated button-style adaptive switch. The design includes three main components, a circular raindrop shaped base unit, a cap (the activation surface), and the internal microswitch. The cap is 0.75 inches in diameter, with the entire switches width measuring at 0.875". The switch is less than 1/2 inch tall. It utilizes the industry standard 3.5-mm mono jack attached to a 3-foot cable. A simple press on the top plate will provide a switch closure with a solid audible 'click' feedback. **$20 replacement cost.
