Abstract: A limit switch assembly includes a housing having a first end, a second end, an inner surface that defines an inner volume and a spring engagement surface, and an outer surface. A limit switch disposed within the inner volume includes a threaded bushing section at least partially extending from the first end. A spring within the inner volume surrounds the bushing section, and engages the limit switch and the spring engagement surface. A calibration nut threaded onto the bushing section engages the first end of the housing. A seal divides the inner volume of the housing into a first volume and a second volume. A drain hole formed in the housing fluidly communicates the first volume to a surrounding environment. A terminal assembly connected to the second end of the housing seals the second volume from the surrounding environment.

Abstract: A drive-by-wire non-contact capacitive throttle control apparatus and method of forming the same. A capacitive position sensor is provided, which includes a stationary electrode and a rotatable electrode. The rotatable electrode can be attached to a throttle lever such that the rotatable electrode rotates as the throttle lever rotates. The capacitance between the rotatable electrode and the stationary electrode varies with the position of the throttle lever. The position of the throttle lever can be measured by measuring the capacitance between the electrodes and a signal can be generated based on the sensed position. The signal can be electrically transmitted to an ECU (Electronic Control Unit) utilizing one or more electrical wires. The signal can be sent in the form of a varying voltage, which in turn controls the throttle of a vehicle.
