  • Patent number: 5563355
    Abstract: A force sensing device providing an output signal indicative of applied force includes a compressible spring, preferably a Belleville type spring, inserted between a force application lever and a reaction force member and the spring is compressed when a force is applied to the lever. In one embodiment, the reaction force member is a push rod and the spring is disposed in a housing attached to a pin on the force lever and the push rod is provided with a longitudinally extending slotted opening in the area of the force pin such that the spring is compressed when the force pin is moved in the elongated area of the push rod. In another embodiment, the spring is disposed in a housing having one end connected to the force lever and a reaction force push rod engages the housing in an opening at its other end and the spring is compressed against the push rod when a force is applied to the force lever.
