<p>A keypad assembly (300) is described herein in which the keypad assembly (300) includes a substrate (200) and a plurality of domes (302) positioned on the substrate (200) and configured to translate operator action into a corresponding input for a machine. The keypad assembly (300) also includes a dome overlay (330) positioned over the domes (302) and the substrate (200) in which the dome overlay (330) can create a sealed environment for the substrate (200) and the domes (302). A light guide (320) that directs light in the keypad assembly (300) and an interlocking component (335) coupled to the light guide (320) can also be part of the keypad assembly (300). In one arrangement, the interlocking component (335) can selectively compress the dome overlay (330) to assist in the creation of the sealed environment. In another arrangement, the interlocking component (335) can compress the dome overlay (330) by bending the dome overlay (330) at an edge (210) of the substrate (200).</p> |
