Abstract: C-, T- and S-switches have a connector or reed (216,220) in each conducting path. The connector or reed contains a support (230) for a permanent magnet (224, 228). All of the magnets (224, 228) of the connectors (216, 220) have the same polarity. The connectors, supports (230) and permanent reed magnets in the supports are contained within an RF cavity housing (204), which is completely sealed from an actuator (208). The actuator has a circular shape and contains permanent magnets (236, 238) that correspond in their configuration to the reed magnets of the housing. At least two magnets of the actuator have different polarities. The actuator can be rotated by a motor (210) to two or more positions. In one position, one or more of the reed magnets are attracted and one or more of the reed magnets are attracted and one or more of the reed magnets are repelled. The switch is designed so that when a reed magnet is attracted, the conducting path in which the connector is located is interrupted and when a reed magnet is repelled, the conducting path is connected. Previous switches are more expensive to manufacture and more complex, thereby increasing the likelihood of premature failure. Previous switches do not have a housing that is completely sealed from an actuator.

Abstract translation: C，T和S开关在每个导电路径中都有一个连接器或簧片（216,220）。 连接器或簧片包含用于永磁体（224,228）的支撑件（230）。 连接器（216,220）的所有磁体（224,228）具有相同的极性。 支撑件中的连接器，支撑件（230）和永久性簧片磁体容纳在RF致动器壳体（204）内，其完全与致动器（208）密封。 致动器具有圆形形状并且包括在其构造中对应于壳体的簧片磁体的永磁体（236,238）。 致动器的至少两个磁体具有不同的极性。 致动器可以通过马达（210）旋转到两个或更多个位置。 在一个位置中，一个或多个筘磁体被吸引并且一个或多个筘磁体被吸引，并且一个或多个筘磁体被排斥。 开关被设计成使得当簧片磁体被吸引时，连接器所在的导电路径被中断，并且当簧片磁体被排斥时，导电路径被连接。 以前的开关制造成本更高，更复杂，从而增加了过早失效的可能性。 以前的开关没有一个完全从执行机构密封的外壳。
