摘要： In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its face. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into electric contact with a stationary electrical contact that is connected to a source of electric potential or, in the alternative, to relieve one of the contacts from being pressed onto the stationary contact. An index wheel mounts to the shaft and has equiangularly spaced grooves. A plastic spring having parallel legs is mounted on the base of the switch. The legs have convex detents which register in successive grooves as the rotor is indexed rotationally in a stepwise fashion. The radius of the detents is greater than the radius of the grooves between the teeth of the index wheel. The legs of the spring are prohibited from moving longitudinally and tension is maintained in the spring legs at all times.
摘要翻译：在旋转开关中，手动旋转的轴转动在其一个面上具有多个立管凸轮段的盘。盘的逐步旋转导致凸轮段向下按压布置在开关中的扁平弹簧触点，以便将一个触点的尖端一次放置成与连接到电位源的固定电触点电接触，或，或者，为了减轻其中一个触点被压在固定触点上。分度轮安装到轴上并具有等角度间隔的凹槽。具有平行腿的塑料弹簧安装在开关的底座上。当转子以逐步的方式旋转地转位时，腿具有在连续的凹槽中对准的凸形棘爪。棘爪的半径大于分度轮齿之间凹槽的半径。弹簧的腿部被禁止纵向移动，弹簧腿总是保持张力。

摘要： In a rotary switch, a manually rotatable shaft turns a disk which has a plurality of riser cam segments on one of its faces. Stepwise rotation of the disk causes the cam segments to press down on flat spring contacts arranged in the switch to put the tip of one of the contacts at a time into contact with a stationary electrical contact bar that is coated with a noble metal. The spring contacts are configured such that when pressed by a cam the tips are caused to make contact with the stationary contact bar and then slide longitudinally so as the tip will pick up some of the noble metal coating from the contact bar. The tips are shaped with a traverse curve intersecting a longitudinal groove to thereby produce two points that make high unit stress contact with the stationary contact bar.
摘要翻译：在旋转开关中，可手动旋转的轴转动在其一个面上具有多个立管凸轮段的盘。盘的逐步旋转使得凸轮段向下按压布置在开关中的扁平弹簧触点上，以使其中一个触点的尖端一次与被贵金属涂覆的固定电接触杆接触。弹簧触点被构造成使得当被凸轮按压时，使尖端与固定接触杆接触，然后纵向滑动，从而尖端将从接触杆拾取一些贵金属涂层。尖端通过与纵向槽相交的横向曲线成形，从而产生使高单位应力与固定接触杆接触的两个点。
