A pressure switch of this invention comprises a base electrode , a terminal , a disc and a diaphragm . The base electrode has a switching chamber for inserting the contact part of the terminal . The switching chamber is sealed with an insulation member at one side. The disc is formed so as to be able to contact with the contact part of the terminal while it is connected to the base electrode and to be able to inverse under a predetermined magnitude of pressure. The diaphragm is made of a metal and is fixed to the base electrode so as to keep vacuum of the switching chamber including the contact part and the disc by sealing the opening of the switch chamber at other side.
