Abstract: In normal operation, the rising diaphragm raises the actuator and spring seat against the force of the reset spring. Just before reaching the trip point of the switch in one form, the seat engages the strip spring eyelet so the pressure is opposed by both springs, the force of the trip spring- and, hence, the operating pressure of the switch- being determined by the position of the plunger. As the pressure decreases under the diaphragm, the eyelet bottoms in the well before reset so the reset force on the diaphragm is determined by the reset spring only. At extra low level settings the plunger is allowed to rise until the spring lifter is picked up by the plunger- to cancel out the force of the trip spring- and lifted a little by the reset spring so the seat cannot engage the eyelet before the trip point. Therefore, at this setting the diaphragm is opposed only by the reset spring. The second modification differs in that the reset spring is affected by the trip spring adjustment.

Abstract: When the plunger is depressed, the actuating blade acts on the cam to rotate the cam detent and wiper assembly 60*. The rotating detent cooperates with the fixed detent to give the ''''feel'''' and indexing action. The fixed contacts are arranged so one of the three wipers will always contact a ''''hot'''' contact while one of the wipers will contact either the low beam or high beam contacts in the static (detented) position. During the switching action, which occurs after the detent action starts and, therefore, at high speed, there is always an interval when both the high and low beam contacts are engaged by the wipers to make the new circuit before breaking the old circuit. The ''''hot'''' circuit is never broken and arcing is minimized. The use of three blades instead of two increases switch life. And safety is improved since there is no time during which no headlamp circuit is made.

Abstract translation: 当柱塞被压下时，致动叶片作用在凸轮上以使凸轮制动器和刮水器组件旋转60度。 旋转棘爪与固定棘爪配合，提供“感觉”和索引动作。 固定触点布置成使得三个擦拭器中的一个将总是接触“热”触点，而其中一个擦拭器将接触静态（定位）位置中的近光束或远光触头。 在开启动作之后，在制动动作开始之后发生，因此在高速时，总是有一个间隔，当高和低光束接触都被擦拭器接合以在断开旧电路之前制造新电路。 “热”电路绝对不会损坏，并且电弧最小化。 使用三个刀片而不是两个刀片可以增加开关寿命。 安全性得到改善，因为没有时间，没有头灯电路。
