好，我现在挂苹果了啊，一部分是铁，还有磁铁，我把开关开开，磁铁启动了。
Okay so now I am going to bring the apple up there's some metal here, there are electromagnets and so I throw a switch here so that the electromagnet is activated.
浮子上的磁铁与弹簧开关相关联。
The magnets on the float close the associated reed switches.
包装：散装包装，10个开关和磁铁对每包。
Packaging: Bulk packaging, 10 switch and magnet pairs per package.
作为简单描述，提供给比例阀电磁铁的电流需要被调节，不象应用常规阀的时仅有开关通或断那样简单。
As described earlier, the electrical current to the solenoid of a proportional valve needs to be regulated and not just simply switched on or off as is the case with a conventional valve.
作为无锈、无蚀管，它的性能是一流的，同时也带来了另一个好处。我们可以放置一个磁铁在活塞处，操作拉杆有限开关——这是一个独特的功能！
As a no-rust, non-pitting tube it is superb, yet it brings even further benefit: We can fit the piston with a magnet and operate tie-rod mounted limit switches - a unique feature!
接近开关的特点是以细小的开关体积达到最大的检测距离。它能检测磁性物体(一般是永久磁铁)，然后产生触发开关输出。
Close to the switching characteristics of the switch size is small, maximum detection distance. It can detect magnetic objects (usually permanent magnet), and then generate the output trigger switch.
请注意，这些开关是与年纪较大的风格馆拉杆气缸（磁代码3选择）起磁铁外，所有纽曼帝克磁铁兼容。
Please note that these switches are compatible with all Numatics magnets with the exception of older style Hall effect magnets for tie rod cylinders (magnet code 3 option).
提出利用开关电磁铁构成单电磁铁式电液比例伺服阀的方案。
A new scheme for electrohydraulic proportional servo valves with switching solenoids was presented.
在距离钢筋出料口一定距离的延长线上设有一个接触式行程开关，行程开关与离合器电磁铁之间连接有导线。
An extension line with a certain distance to the steel bar discharge hole is provided with a contact travel switch. A wire is connected between the travel switch and a clutch electromagnet.
