<p>A switch matrix (20) is disclosed for keypads (10) used in devices such as primary control points for automation systems in homes vehicles, or businesses. The switch matrix (20) preferably includes a support frame (22) for supporting a grid of key positioning members (28) arranged in a series of rows and columns. The key positioning members (28) each preferably include cantilevers (30,34) which can be deflected by pressing the keys (12) to activate switches (67) associated with the keypad (10). The cantilevers (30,34) preferably have knobs (44) which are received in corresponding openings (46) in the keys (12) so that the keys (12) can be removably attached to the cantilevers (30,34) with a compression fit. This allows keys (12) of different sizes and shapes to be easily attached to the keypad (10) in various configurations without the need for different attaching devices for each situation.</p> |
