In industrial and automotive applications, it is frequently necessary that, when the pressure setting is reached, this is converted into an electrical signal that starts a machine cycle or indicates a certain situation (e.g. system leaks or alarms).
These operations are generally controlled by components, called PRESSURE SWITCHES, that are calibrated according to the specific application.
