摘要： A vacuum switch in which the diaphragm movement with increasing vacuum is opposed by two springs which determine the vacuum required to actuate the switch. As the vacuum subsequently decreases one of the springs is rendered inoperative before the switch resets so the reset vacuum is determined by the one spring remaining effective. The spring which is rendered inoperative is compressed between the actuator and an eyelet which can seat on the actuator (spring ineffective) or the housing (spring effective) and which also functions to limit motion of the actuator relative to the eyelet so the switch operated by the actuator cannot be overstressed.
摘要翻译：一个真空开关，其中隔膜运动随着真空度的增加而相反，两个弹簧决定了启动开关所需的真空度。随着真空随后减少，在开关复位之前，弹簧之一变得不起作用，因此复位真空由一个弹簧保持有效决定。不可操作的弹簧被压缩在致动器和可以位于致动器上的孔眼（弹簧无效）或壳体（弹簧有效）之间，并且还用于限制致动器相对于孔眼的运动，使得开关由执行器不能过压。

摘要： An instrument with an illumination ring that edge-lights an opaque dial face with increased light flow by augmenting the conductivity of both the light receiving portion of the ring and a bevel for deflecting light laterally across the face. The increased light flow is accomplished by an extended annular wall portion spaced from the edge of the dial face.
