    摘要： A key assembly for use in an electronic device is provided. The key assembly includes a plurality of dome switches and a plurality of single-piece keycaps. Each keycap identifies a row of keyboard characters. Each keycap has a plurality of character-representing portions separated by deforming portions. Each character-representing portion is associated with a separate one of the plurality of dome switches. The key assembly further comprises a plurality of actuators for activating the dome switches. Each actuator has a first side which is engaged by one of the character representing portions of the keycap. Each actuator has a second side which engages the dome switch associated with that character-representing portion. In a rest state in which the keycap is not depressed, at least some of the actuators preload at least some of the dome switches by exerting a force upon the dome switches.

    摘要翻译： 提供了一种用于电子设备的按键组件。 钥匙组件包括多个圆顶开关和多个单件钥匙盖。 每个键帽标识一行键盘字符。 每个键帽具有由变形部分分开的多个字符代表部分。 每个字符代表部分与多个圆顶开关中的单独的一个相关联。 钥匙组件还包括用于致动半球开关的多个致动器。 每个致动器具有由键帽中的一个字符代表键帽的部分接合的第一侧。 每个致动器具有接合与该字符代表部分相关联的圆顶开关的第二侧。 在没有按压键帽的静止状态下，至少一些致动器通过对圆顶开关施加力来预先加载至少一些圆顶开关。
