[0002] The word switch is interpreted as opening and closing. It also refers to an electronic component that can open a circuit, interrupt the current or make it flow to other circuits. The crank, as a component of the switch, plays an important role in the use of the switch.

[0003] The existing switch crank has some shortcomings when in use. For example, the existing switch crank cannot fix the position of the crank when in use, and it is often misoperated and causes inconvenience in use. The rotating part at the bottom of the crank is connected to the metal, which will rust due to oxidation over time, making the crank inoperable. If the crank is broken or has problems, the switch panel must be opened to check and repair the crank, which makes maintenance inconvenient and may cause damage to other parts in the switch.
