US Patent 11609637 Switch assembly with integrated haptic exciter

A switch assembly that provides haptic feedback includes a printed circuit board (PCB) having a first planar surface that faces in a first direction and a second planar surface that faces in a second direction, the second direction being opposite from the first direction, a touch plate having a first surface that faces in the first direction and a second surface that faces in the second direction, wherein the first surface of the touch plate is proximate the second planar surface of the PCB, and a haptic exciter that has a conductive coil of wire having a hollow inner core and a magnet that is at least partially disposed within the hollow inner core of the coil of wire such that the magnet alternatively moves in the first and second directions as an alternating current passes through the conductive coil of wire.
