1. A pressure switch arrangement comprising:
a pressure switch body defining a chamber, the pressure switch body also having a fitting end defining a conduit leading to the chamber;
a switching component disposed within the chamber of the pressure switch body, the switching component including a trigger;
an actuation unit disposed within the chamber and being movable relative to the switching component, the actuation unit extending along a length between a first end and a second end, the first end facing the fitting end and the second end facing the trigger, the actuation unit including a limiter disposed at an intermediate position between the first end and the second end, the actuation unit also defining a spring stop region disposed between the limiter and the second end;
a first insert disposed within the chamber of the pressure switch body, the first insert defining a first aperture through which the actuation unit extends so that at least a portion of the first insert is disposed between the limiter and the spring stop region of the actuation unit, the first insert cooperating with the pressure switch body to define a pocket into which the limiter radially extends, the limiter being movable within the pocket as the actuation unit moves within the chamber, the first insert being threadably mounted to the pressure switch body within the chamber;
a spring arrangement engaging the spring stop region of the actuation unit, the spring arrangement biasing the actuation unit away from the trigger of the switching component; and
a second insert disposed within the chamber of the pressure switch body, the second insert being configured to support the spring arrangement, the second insert defining a second aperture through which the actuation unit extends.
