Patent ID: 10741343

Abstract:
A keypad device includes a circuit board having raised buttons disposed on a first surface of the circuit board, resilient switches disposed on a periphery of the first surface, and through-holes, wherein each of the raised buttons and switches, when actuated, closes a circuit on the circuit board and affects an input to the device. The keypad device includes a faceplate fastened to the circuit board, the faceplate having an array of openings configured to allow the buttons to pass through, bosses extending from a first surface of the faceplate toward the circuit board and positioned to pass through the through-holes on the circuit board, and plungers aligned above and in contact with the resilient switches such that when the plate is pressed toward the circuit board, in a region at or near a subject plunger, the subject plunger actuates the resilient switch that is in contact with the plunger.
