    摘要： A hermetically sealed switch with multiple switching positions comprises an actuator welded or soldered to a metallic diaphragm. The diaphragm is in turn welded or soldered to the inner walls of the switch housing. The diaphragm is flexible and allows the actuator to pivot about the welded portion. The pivoting motion causes rotation at each end of the actuator. Therefore, if one end of the actuator is rotated, the other end will similarly rotate about while the weld between the actuator and the diaphragm remains intact. The sealed end of the actuator is inserted into a rotor. The rotor has a metal piece which rotates in a circular manner and couples individual contacts to a common electrical ground. Each contact represents a different switch setting. As the metal piece of the rotor couples the contact with the ground, current is allowed to flow between the two and the setting represented by the contact is selected. Electrical leads couple the contacts and the ground to the sealed host device.

    摘要翻译： 具有多个开关位置的气密密封开关包括焊接或焊接到金属隔膜的致动器。 隔膜又被焊接或焊接到开关壳体的内壁。 隔膜是柔性的并且允许致动器围绕焊接部分枢转。 枢转运动在致动器的每个端部引起旋转。 因此，如果致动器的一端旋转，则在致动器和隔膜之间的焊接保持完整的同时，另一端将类似地旋转。 致动器的密封端插入转子。 转子具有以圆形方式旋转的金属片，并将单个接触件连接到公共电气接地。 每个触点代表不同的开关设置。 当转子的金属片与地面接触时，允许电流在两者之间流动，并且选择由触点表示的设定。 电气引线将触点和接地耦合到密封的主机设备。
