The pressure switches tend to be fitted to the older standard efficiency boilers Pressure switches can relate to water, gas or air and are used to restrict or allow the flow of specific material dependent on the pressure variables they are designed to switch the boiler off if the pressure in the boiler falls below a pre-set pressure normally 0.5 bar or 0.25 bar of pressure. This prevents the boiler from running at low pressures which prevent damage to the boiler. A pressure transducer is an electronic device and monitors the pressure all of the time and turns the boiler off if the boiler falls below 0.5 bar or 0.25 bar but it also turns off the boiler if the pressure gets too high within the boiler and this is normally set at around 2.75 bar.
