    摘要： 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.

    摘要翻译： 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。

    摘要： Each of the two refrigeration systems incorporates an electric evaporator temperature control regulated by a solid state temperature switch which may be adjusted for a desired temperature and may be located in a remote location. In one system the control valve is located in the suction line between the evaporator and compressor and functions to throttle flow to the compressor when the temperature at the thermistor sensing probe falls below the set point. In the other system the temperature control valve functions as a hot gas bypass valve from the compressor outlet to the suction line between the evaporator and the compressor. The valve is opened when the temperature at the thermistor sensing probe falls below the set point. In either system operation of the temperature control valve acts to control pressure in the evaporator and thus controls the temperature. With the sensor located in the air stream, the system functions to control the air stream temperature and will compensate the system for frost build-up on the evaporator. The temperature control valve itself is preferably a ported sleeve-type valve actuated by a bimetallic stack energized by a heater regulated by the remote temperature sensing control. The temperature control includes a thermistor which forms part of an adjustable branch of a bridge circuit, the output of which is fed into a signal amplifier which, in turn, feeds into a power amplifier to give a desired voltage change per a selected increment of temperature deviation from the set point. In addition to giving remote sensing and adjustability, this system achieves close temperature control and more rapid pulldown of the system since there is a minimal modification of evaporator temperature/pressure until the desired temperature is reached. When used in a display case the system can incorporate an added resistance and switch to shift the set point to compensate for changed ambient conditions.
