Magnetism switch also is called magnetic switch, it is fluid of magnetism platform trap door plan optional sex fittings. Its are the biggest the characteristic can make namely fluid of magnetism platform trap door plan accuse with be being held remotely fluid, be about to fluid of magnetism platform trap door plan fluid measure mode to change a switch quantity mode, practical effect and content switch is not had 2 send, but because of fluid of magnetism platform trap door plan the juice that face plate can display instantly in real time circumstance, because this is become magnetism switch and fluid of magnetism platform trap door plan when assorted form a complete set is used, bring appearance staff member extremely tall advantage, promote the job the efficiency of the spot considerably. The core component of magnetism switch is canal striking spring, at first, two reed were not contacted, but should be in when the magnetic field that produces through permanent magnet or electromagnetism coil, adscititious magnetic field can make different polarity arises near position of two reed end points, if magnetic force exceeds the elastic force of reed itself when, these two reed can be sucked close guide electrify road; If magnetic field is abate or move disappear, dry reed is released as a result of the flexibility of itself, interface can part thereby open circuit. Regard platform trap door of Flap-11 series magnetism as fluid plan fittings, guan Yuanchuan of dry spring of SW-11 magnetism switch and Reed-11 changes send implement supplement each other, not only can fluid of magnetism platform trap door plan essence of life of metrical real time data communicates monitoring room definitely, the fluid with long-range implementation monitoring, still can output switch signal, prevent fluid spill over and work to move or realize fluid of on any account call the police. Be worth what carry is, guan Yuanchuan of dry spring of SW-11 magnetism switch and Reed-11 changes send implement before appearing on the market oneself already in pairs carries Chinese oil and chemical industry quality of electric product explosion proof is supervised examine center (PCEC) install explosion proof attestation originally, obtain the explosion proof certificate of conformity of national level, fluid of safeguard magnetism platform trap door plan the explosion proof that can apply in petro-chemical industry reliably is special environment.
