US Patent 10032592 Force sensing switch

A force sensing switch for use in an electronic device can include one or more dome switches disposed over a top surface of a deflectable beam. One or more strain gauges can be disposed over at least one surface of the deflectable beam. An electronic device that includes at least one force sensing switch can further include a processing device operatively connected to the one or more strain gauges. Alternatively or additionally, an electrode can be disposed under a bottom surface of the deflectable beam and a capacitance measured between the bottom surface and the electrode.
