摘要： A gravity-actuated switch having a switch module with a switch housing and a lid. An electrically conductive pendulum is pivotally secured to the lid via a pivot pin so that the pendulum hangs within the housing and pivots with respect to the housing under the influence of gravity. A first electrical contact connectable to a power source abuts the pivot pin, which is electrically conductive. A second electrical contact is provided within the housing in a predetermined position such that the pendulum makes contact with it when the switch module is tilted by a predetermined amount. When the pendulum makes contact with the second electrical contact, a short circuit is provided across the pair of contacts, thus closing the switch. The switch is incorporated in a lamp assembly provided on the underside of the hood or trunk lid of an automobile to selectively provide power to a lamp so that the lamp is illuminated only when the hood or trunk lid is opened by at least a predetermined amount. A switch composed of a pivoting magnet and a magnetic switch can be used instead of the combination of the conductive pendulum and the curved electrical contact.
摘要翻译： 具有开关模块的重力驱动开关，其具有开关壳体和盖子。 导电摆通过枢轴销枢转地固定到盖子上，使得摆锤悬挂在壳体内并且在重力的影响下相对于壳体枢转。 可连接到电源的第一电触头抵靠导电的枢轴销。 第二电触点设置在壳体内的预定位置，使得当开关模块倾斜预定量时，摆锤与其接触。 当摆与第二电触点接触时，跨越该对触点提供短路，从而闭合开关。 开关装在设置在汽车的发动机罩或行李箱盖的下侧上的灯组件中，以选择性地向灯提供电力，使得只有当发动机罩或行李箱盖打开至少预定量时，灯才被照亮。 可以使用由枢转磁体和磁性开关构成的开关来代替导电摆和弯曲的电接触的组合。
