  • Patent number: 7858892
    Abstract: A latching and electrical switch mechanism includes an insulated housing having a cavity therein with an opening thereto along with an electrically conductive ball disposed therein. The ball includes a stem with a smaller diameter than the ball and extends therefrom with a ball being sized for rotational and translational movement within the housing cavity. At least one groove is provided in the housing cavity and a coil spring is disposed in a groove for making electrical contact with the ball and retaining the ball for rotation within the cavity with the stem at selected conical angles with respect to the housing centerline. At least one electrical contact is disposed in the cavity at a spaced apart relationship with the coil spring for providing electrical connection with the ball upon translational movement of the ball within the cavity, which also produces an audible sound.
