    • A self regulating heated switch assembly is provided for heating the interior of a switch housing so as to prevent freezing of switch contacts therein. The switch assembly includes a switch housing, an insulative cover member, and a PTC heater device. The switch housing includes top, bottom, front, rear and end walls. The insulative cover member is formed of opposed front and rear panels. The front and rear panels are disposed in a spaced apart relationship to the corresponding front and rear walls of the switch housing. The heater device is sandwiched between the front wall of the switch housing and the front panel of the cover member and between the rear wall of the switch housing and the rear panel of the cover member so as to transmit heat into the interior of the switch housing.
    • 提供自调节加热开关组件,用于加热开关壳体的内部,以防止其中开关触点的冻结。 开关组件包括开关壳体,绝缘盖构件和PTC加热器装置。 开关壳体包括顶部,底部,前部,后部和端部壁。 绝缘盖构件由相对的前面板和后面板形成。 前面板和后面板以与开关壳体的对应的前壁和后壁隔开的关系设置。 加热器装置被夹在开关壳体的前壁和盖构件的前面板之间以及开关壳体的后壁和盖构件的后面板之间,以便将热量传递到开关壳体的内部 。

    • A motion translation mechanism is adapted for use in a vehicle seat-operated switch and is selectively responsive to the presence or absence of a downward vertical force. The motion translation mechanism includes a switch assembly having a plunger, a leaf spring, and coil spring. The coil spring is used to resiliently bias a first end portion of the leaf spring against a first stop. The second end portion of the leaf spring is operatively connected between a second stop and the plunger for moving laterally the plunger to a retracted position in response to the downward movement of an upwardly convexed central portion of the leaf spring so as to electrically actuate the switch assembly.
    • 运动平移机构适于在车辆座椅操作的开关中使用,并且选择性地响应下垂的垂直力的存在或不存在。 运动平移机构包括具有柱塞,板簧和螺旋弹簧的开关组件。 螺旋弹簧用于将片簧的第一端部弹性偏置抵靠第一挡块。 板簧的第二端部可操作地连接在第二止动件和柱塞之间,以响应于片簧的向上凸起的中心部分的向下运动而将柱塞横向移动到缩回位置,以便电动致动开关 部件。
