Check out the Michrotechnologies Switch Challenge video here: https://youtu.be/oYXZYM-2krU The spiral-shaped diaphragm ensures a wide range of pressure adjustability and heightened sensitivity, while its micro pattern expands the active surface area compared to a flat design. The switch's body can be 3D printed, with advanced printers even capable of producing integrated electrical components. It functions as both a positive pressure and negative (vacuum) switch, consisting of just eight parts in total.
