When should you choose a mechanical pressure switch so when should you rather choose for an electronic pressure switch? Each switch principle offers advantages, but also has its limitations. Among other things, you can find differences in the application 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 bound and only individual switch points are needed. They are often used in safety-critical applications where they have yet another or redundant safety function. While they remain idle for some time, they transmit an instantaneous 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, because they are often suffering from mechanical wear, causing signal drift as well as premature failure.

Electronic pressure switches are used where several switch points and the stability and flexibility of the control are essential. They are perfect 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 essential, electronic pressure switches are the primary choice.
