A position sensor for sensing whether a rotatable element is in at least a first rotational position or a second rotational position is provided. A rotor is configured to be coupled to the rotatable element for rotation therewith, and is constructed at least partially of a magnetically permeable material and includes a first rotor pole. A stator is non-rotationally mounted, is constructed at least partially of a magnetically permeable material, is spaced apart from the rotor, and comprises a first main pole and a first stealer pole. The first main pole and the first stealer pole are spaced radially apart from each other. A magnet is non-rotationally disposed adjacent to the stator and is spaced apart from the rotor. A first magnetic sensor is non-rotationally mounted between the stator and the rotor, is disposed adjacent the first main pole, and is radially offset from the first stealer pole.

A hermetically sealed pressure switch apparatus and method includes a metal bellows directly installed at an inlet port for providing hermetic sealing thereof. A spring (e.g. a wave spring) can be connected in parallel or series combination with the metal bellows. The metal bellows is capable of being extended when an input pressure is applied which in turn compress the wave spring. The compression of the spring transfers a required motion to a plunger associated with an electrical switch in order to actuate the electrical switch when a certain pressure relative to a perfect vacuum is attained. The metal bellows and the spring can be pre-compressed utilizing the plunger in order to maintain switch set point accuracy and spring stiffness.
