Description

Multi-knife rotary switch

Technical Field

The utility model relates to the technical field of switches, in particular to a multi-knife rotary switch.

Background

The term switch is interpreted as on and off. 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 switch is a human operated electromechanical device in which there are one or several electronic contacts. The "closed" of the contacts means that the electronic contacts are conductive, allowing current to flow; an "open" switch indicates that the electrical contact is not conducting to form an open circuit and no current is allowed to flow.

The rotating hand feeling of the existing multi-knife switch is the same, so that whether the switch rotates in place or not is inconvenient to judge, and misoperation is easy to occur. To this end, we propose a multi-knife rotary switch.
