Abstract

A seating switch device is a switch mechanism comprising a magnet (23) and a reed contact switch (24), wherein the magnet performs switching operation through deformation of a diaphragm 20. The switch mechanism enables the magnet (23) to be fixed to the diaphragm (20) facing one side of a pressure chamber (21). The reed contact switch (24) keeps parallel to or substantially parallel to the magnet (23) along the length to be opposite to the magnet. The relative space between the magnet (23) and the reed contact switch (24) is changed on the basis of deformation of the diaphragm (20), so that the switch mechanism can perform switching operation.

Description

technical field

[0001] The invention relates to a seat switch device for detecting the pressure difference of a pair of pressure chambers divided by membrane components such as diaphragms. Background technique

[0002] As such a switch device, the structure described in Patent Document 1 is conventionally known, and in Figure 4 The outline of this conventional switchgear is shown in .

[0003] Figure 4 In the shown conventional switching device, a diaphragm 2 is provided in a housing 1 , which divides the interior of the housing 1 into a pair of pressure chambers 3 , 4 . The diaphragm 2 is provided with folds 2 a on its outer side so as to be deformable according to the pressure difference between the pressure chambers 3 and 4 .

[0004] In addition, reference numeral 5 in the figure is a pressure introduction port for introducing pressure into one pressure chamber 3 , and 6 is a pressure introduction port for introducing pressure into another pressure chamber 4 . [000...
