Abstract:
A position sensor operable to sense the movement of an attached object, comprising:a) a housing having a cavity;b) a shaft, located in the cavity and extending out of the cavity into contact with the object;c) a substrate, disposed in the cavity, the substrate having a first side and a second side;d) a strain gauge resistor, located on the second side of the substrate; ande) a spring, located between the shaft and the substrate, the spring having a first end retained by the shaft and a second end disposed adjacent the first side of the substrate so that the spring is compressed and decompressed as the object moves, the spring compression and decompression causing the substrate to be stressed and the resistor to change resistance, the resistor protected from contact with the spring by the substrate.
