Mechanical vs electronic pressure switches: Application areas

When should you choose a mechanical pressure switch and when should you rather decide for an electric pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other activities, there are differences in the application areas for mechanical and electronic pressure switches. Considered of this will give you support in your selection.
Application areas for mechanical pressure switches
Mechanical pressure switches tend to be used when the budget is bound and only individual switch points are needed. They are often found in safety-critical applications in which they have an additional or redundant safety function. While they remain idle for a long time, they transmit an immediate switching signal when the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches aren’t the first choice in electronic systems, because they are often suffering from mechanical wear, causing signal drift as well as premature failure.
Application areas for electronic pressure switches
Electronic pressure switches are used where several switch points and the stability and flexibility of the control are important. They are perfect for automated equipment and control systems where programmable switches are preferred, as the desired setting for the switch point may change over the years. Whenever additional analogue output signals, an area indication by display or flexible adjustment and programming are needed, electronic pressure switches are the primary choice.
