Description

Technical Field

[0001] This utility model relates to the field of switches, specifically to a novel dustproof and waterproof switch. Background Technology

[0002] A switch is an electronic component that can open a circuit, interrupt current, or divert current to another circuit. The most common type of switch is a human-operated electromechanical device with one or more electronic contacts. A "closed" contact indicates that the electronic contacts are conducting, allowing current to flow; an "open" contact indicates that the electronic contacts are not conducting, forming an open circuit and preventing current from flowing. A drawback of existing switches is their limited waterproof and dustproof performance, making them susceptible to entry of external dust and water, which can affect their normal operation.
