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.

In a first aspect of the present disclosure, a push switch includes a substrate including a first electrode and a second electrode arranged on an upper surface of the substrate, the second electrode arranged around the first electrode; and a resilient member that is arranged on the second electrode over the first electrode. The substrate includes a recess in a lower surface of the substrate, and the recess is positioned below the first electrode that is arranged on the upper surface of the substrate.

A switch unit includes a wiring board, a spacer, a movable contact element, a pressing element, and a protective sheet. A first stationary contact element and a second stationary contact element having rectangular shapes are provided on an upper surface of the wiring board. A contact section includes the movable contact element, the first stationary contact element, and the second stationary contact element. The movable contact element is mounted on a portion of the upper surface of the wiring board that is exposed from an inside of an opening of the spacer so that an outer edge of the movable contacts the second stationary contact element. The first stationary contact element continuously extends from a region of the wiring board facing a movable contact portion of the movable contact element to a region of the wiring board outside a region of the wiring board onto which the movable contact element is projected.
