PROBLEM TO BE SOLVED: To provide a seating switch having a high detection accuracy of a differential pressure.SOLUTION: A seating switch device comprises a switch mechanism performing a switching operation by deformation of a diaphragm 20, and consisting of a magnet 23 and a lead switch 24. In the switch mechanism, the magnet 23 is fixed to the diaphragm 20 facing one pressure chamber 21 side. The lead switch 24 is opposed to the magnet while keeping the longitudinal direction in parallel or substantially in parallel to the magnet 23, and changes an opposing interval between the magnet 23 and the lead switch 24 depending on the deformation of the diaphragm 20 to make the switch mechanism perform the switching operation. |
