Mechanical vs electronic pressure switches: Application areas

When if you undertake a mechanical pressure switch and when should you rather choose 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.
Application areas for mechanical pressure switches
Mechanical pressure switches are often used once the budget is limited and only individual switch points are needed. They are often used in safety-critical applications in which they have an additional or redundant safety function. While they remain idle for a long period, they transmit an immediate switching signal when the pressure exceeds the preset critical switch point pressure. For process control, however, mechanical pressure switches are not the first choice in electronic systems, as they are often affected by mechanical wear, causing signal drift or even premature failure.
Application areas for electronic pressure switches
Electronic pressure switches are employed where several switch points and the stability and flexibility of the control are essential. They are ideal 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 will be the primary choice.
