磁性开关意思就是通过磁铁来感应的，这个“磁”就是磁铁，磁铁也有好几种，市场上面常用的磁铁有橡胶磁、永磁铁氧体、烧结钕铁硼等。开关就是干簧管了。干簧管是干式舌簧管的简称，是一种有触点的无源电子开关元件，具有结构简单，体积小便于控制等优点，其外壳一般是一根密封的玻璃管，管中装有两个铁质的弹性簧片电板，还灌有惰性气体。平时，玻璃管中的两个由特殊材料制成的簧片是分开的。当有磁性物质靠近玻璃管时，在磁场磁力线的作用下，管内的两个簧片被磁化而互相吸引接触，簧片就会吸合在一起，使结点所接的电路连通。外磁力消失后，两个簧片由于本身的弹性而分开，线路也就断开了。因此，作为一种利用磁场信号来控制的线路开关器件，干簧管可以作为传感器用，用于计数，限位等等（在安防系统中主要用于门磁、窗磁的制作），同时还被广泛使用于各种通信设备中。在实际运用中，通常用永久磁铁控制这两根金属片的接通与否，所以又被称为“磁控管”。

ltra Line Cartridge-Style Transducers provide better performance than competitive load cells by increasing the operating tension range from 8:1 to 40:1. They also provide more accurate measurement by eliminating electrical disturbances caused by AC drives, servos, and other modern high frequency devices.
