He also has a triggerswitch in his hand which allow this or that boot to release its magnetism, so the foot can be raised.
他同样还有个触发器握在手中以允许这个或那个靴子释放磁场，这样靴子就可以升高。

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 triggerswitch.
Analysis and research were done for the trigger energy and time delay characteristics in the triggering process, using the energy storage and pulse formation trigger circuit to switch on the TVS.
