What is a sealed switch
Sealed switch is a kind of electrical equipment widely used in industry, construction and household fields. It is mainly used to control the on and off of circuits. It also has the characteristics of dustproof, waterproof, explosion-proof and so on. It can still maintain stable working performance in harsh environments, so it is widely used in chemical industry, mining, electric power and other industries. This article will introduce in detail the definition, classification, application scenarios and recent hot topics of airtight switches.
1. Definition and classification of sealed switches
A sealed switch is an electrical switch with a protective shell that can effectively isolate the impact of the external environment on the internal circuit. According to their functions and structures, sealed switches can be divided into the following categories:
| Type | Features | Application scenarios |
|---|---|---|
| Dustproof sealed switch | Prevents dust from entering, suitable for dusty environments | Factory workshops, construction sites |
| Waterproof sealed switch | Waterproof and can be used in humid environments | Bathroom, outdoor equipment |
| Explosion-proof sealed switch | Prevent sparks from causing explosions, high safety | Petrochemical industry, mining |
2. Application scenarios of airtight switches
Sealed switches are widely used in the following fields because of their unique protective properties:
1.Industrial field: In high-risk environments such as chemical industry, electric power, and mining, explosion-proof airtight switches can effectively avoid safety accidents caused by electric sparks.
2.Construction field: Waterproof sealed switches are often used in humid environments such as bathrooms and kitchens to ensure the safety of electricity.
3.Home furnishing field: Dust-proof sealed switch is suitable for household appliances to extend the service life of the equipment.
