。 The hollow interior of the internally hollow housing is divided into a reference pressure chamber and a pressure chamber by a pressure-sensitive rubber diaphragm that reduces the resistance value inside the rubber when pressure is applied. A pressure switch characterized in that it is provided with an introduction path for introducing the pressure, and an electrode that is turned on and off by being brought into contact with and separated from a diaphragm that is inserted into the reference pressure chamber at one end and responds to the pressure in the pressure chamber.
