[0002] A ceramic switch is an electronic component that can open a circuit, interrupt the current, or make the current flow to other circuits. The most common switch is an electromechanical device operated by a person, which has one or several electronic contacts. The "closure" of the contact means that the electronic contact is conducting and allows current to flow through; the "open circuit" of the switch means that the electronic contact is not conducting to form an open circuit and does not allow current to flow through. In order to adapt to the use in special industries such as aerospace and nuclear energy in high-temperature, high-pressure, and nuclear radiation environments, as a high-temperature-resistant switch, the ceramic switch is widely used.
