Pressure Switch 01

The device, with dimensions of 20 x 20 x 6 mm, consists of several components including a casing, diaphragm, circular disk, terminals, and springs. The inlet air enters a chamber where three sides are sealed by the casing while the fourth side is closed by the diaphragm. When pressure within the chamber increases, the diaphragm expands, pushing the circular disk upward over a fixed disk. Copper slide 1, connected to the input terminal, is attached to this moving disk. When the disk moves upwards, slide 1 comes into contact with copper slide 2 (connected to the output terminal), which is positioned above slide 1 with a 0.05 mm gap. This contact allows current to flow from slide 1 to slide 2. Conversely, when pressure decreases, the diaphragm returns to its normal position, and springs attached to the disk at both ends ensure it returns to its original position as well.
