The function of a Pressure Switch is to provide a path for an electrical circuit that is triggered at a certain pressure. Example uses are: •Oil pressure warning light in an automobile •Pump controller (turn well pump on and off) •Air compressor control •Industrial process signaling A pressure switch must have a process connection (usually threaded for a pipe or tube) and an electrical contact that is connected to wires or terminals. They may sense rising or falling pressure and most are adjustable, so the contact will engage (or turn on the electrical circuit) at a desired pressure setting. They can be pneumatic (air and gases) or hydraulic (water, oil or fluids) or even strictly mechanical. The internals can be a diaphragm capsule, a small chamber backed by a spring or a bourdon tube. The contact is usually copper points but can also be a mercury (in glass) tip switch. Unlike Pressure Transducers which give an analog electrical signal proportional to the amount of pressure, these
