Mechanical vs electronic pressure switches: Application areas

When should you choose a mechanical pressure switch and when should you rather decide for an electronic pressure switch? Each switch principle offers advantages, but additionally has its limitations. Among other things, there are differences in the application form areas for mechanical and electronic pressure switches. A consideration of this will give you support in your selection.
Confident for mechanical pressure switches
Mechanical pressure switches are often used when the budget is limited and only individual switch points are needed. They are often found in safety-critical applications in which they have yet another or redundant safety function. While they remain idle for a long time, they transmit an instantaneous switching signal once the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches are not the first choice in electronic systems, because they are often affected by mechanical wear, causing signal drift and even 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 ideal for automated equipment and control systems where programmable switches are preferred, because the desired setting for the switch point may change through 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.
