航空器的拉杆操纵手动开关 性能要求

[中文适用范围]： 给出了用于标称 28 V 直流和 115/200 V 三相、400 Hz 交流系统的两类单孔固定开关的要求。 1 级开关是密封的，比 2 级开关（仅在控制杆入口处密封）适用于更高的海拔和温度条件。 此外，还给出了尺寸、操作、结构、电压和电流额定值、环境、测试、型式测试、生产测试、质量测试、声明和标记的要求。 [外文原描述]： Gives the requirements for two classes of single-hole fixing switches for use in nominal 28 V d. c. and 115/200 V three-phase, 400 Hz a.c. systems. Class 1 switches are sealed and are suitable for higher altitude and temperature conditions than are Class 2 switches, which are sealed only at the lever entry. Furthermore, gives requirements for dimensions, operation, construction, voltage and current ratings, environment, tests, type tests, production tests, quality tests, declarations and marking.
