Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within the invention patent covering scope.
It is a kind of double drive high-speed switch of the present invention refering to attached drawing 1, including by cylinder-shaped magnetic cylinder body and solid respectively
Due to the magnetic cylinder 1 that upper magnetic cylinder lid 11, the lower magnetic cylinder lid 12 on the magnetic cylinder body upper and lower end face are constituted, be equipped in magnetic cylinder 1 static iron core 2,
Dynamic iron core 3 and driving coil, driving coil include first coil 51 and the second coil 52, and dynamic iron core 3 is set to 2 top of static iron core,
Actuator push rod 4 is fixed on the central axis of dynamic iron core 3, the lower end of the actuator push rod 4 passes through dynamic iron core 3 and forms closing operation end
