Description

Electric automatization switch

Technical Field

The invention relates to a switch, in particular to an electric automatic switch.

Background

The words switch are to be interpreted as open and closed. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closed" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" of the switch indicates that the electrical contact is not conductive, creating an open circuit, and not allowing current to flow.

At present, automation in the fields of industry, electricity and the like is increasingly realized, the automation has great advantages in use and production, manpower is saved, the running time of equipment is reduced, but the automation is more limited in the actual running process, a common knob switch cannot be used, the control of an electrical switch can be carried out only in a specified radian range, and the automation degree becomes lower.
