    • A switch matrix is disclosed for keypads used in devices such as primary control points for automation systems in homes vehicles, or businesses. The switch matrix preferably includes a support frame for supporting a grid of key positioning members arranged in a series of rows and columns. The key positioning members each preferably include cantilevers which can be deflected by pressing the keys to activate switches associated with the keypad. The cantilevers preferably have knobs which are received in corresponding openings in the keys so that the keys can be removably attached to the cantilevers with a compression fit. This allows keys of different sizes and shapes to be easily attached to the keypad in various configurations without the need for different attaching devices for each situation.
    • 公开了用于诸如家用车辆或企业中的自动化系统的主要控制点的设备中的小键盘的开关矩阵。 开关矩阵优选地包括用于支撑布置成一系列行和列的键定位构件的格栅的支撑框架。 键定位构件各自优选地包括可以通过按压键来偏转以激活与键盘相关联的开关的悬臂。 悬臂优选地具有被接收在键中的对应开口中的旋钮,使得键可以以压缩配合可移除地附接到悬臂。 这允许不同尺寸和形状的键以各种配置容易地附接到键盘,而不需要针对每种情况的不同的附接装置。
