The button switch may be the simplest component in the electrical circuit, but it controls the lifeblood of the entire control circuit, so it is also called the "master switch". Understanding all kinds of button switches and using them skillfully and flexibly can make us get twice the result with half the effort.
Button switches are used to switch on or off small current circuits in a short period of time, and are mainly used in electrical control circuits. The current allowed to flow through the button switch is small, generally not more than 5A.
The button is generally composed of a button cap, a return spring, a bridge-type moving contact, a static contact, a pillar connecting rod, and a housing. The opening and closing state of the contacts when the button is not subjected to external force (that is, static), is divided into a stop button (that is, a dynamic break button), a start button (that is, a dynamic close button) and a reset button (that is, a combination of a dynamic close and a dynamic break. integrated button). When the button is under the action of external force, the opening and closing state of the contact changes: the normally open contact under static state is closed, and the normally closed contact under static state is open.
