[0002] A switch is an electronic component that can open a circuit, interrupt the current, or flow it to other circuits. The most common switch is an electromechanical device operated by humans, which has one or more electronic contacts. The "closed" contact means that the electronic contact is conducting, allowing current to flow; the "open circuit" of the switch means that the electronic contact is not conducting, forming an open circuit, and does not allow current to flow. The "closed" contact is achieved through the contact bridge contact conduction. In order to increase the stability of the contact bridge contact conduction, it is generally necessary to rivet rivets at both ends of the contact bridge. The head of the rivet is the contact, which can improve the stability of the contact bridge contact conduction.
