| 摘要 | 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. | ||||||
