The reason why the waterproof limit travel switch can have waterproof function mainly relies on the following principles and design points:
Sealing materials: The housing and seals of waterproof limit travel switches usually use high-quality waterproof and sealing materials, such as rubber, silicone, fluororubber, etc. These materials have excellent water resistance and can effectively block moisture penetration.
Tight housing design: The housing of the waterproof limit switch adopts a tight structure design to ensure that external liquids cannot easily enter the internal circuit or mechanical components. Special consideration will be given to the connection points, jacks, switch buttons and other parts of the housing to reduce the possibility of liquid penetration.
Waterproof joints and sealing rings: The connecting joints and openings of waterproof limit switches are usually equipped with waterproof joints and sealing rings. These designs can effectively prevent liquids from entering the interior from connections or openings.
Coating and coating: Some waterproof limit switches will be coated with a special coating on the surface of the housing to enhance its waterproof performance. These coatings prevent moisture from adhering to the surface, thereby reducing the risk of penetration.
Strict waterproof testing: During the production process, waterproof limit switches need to undergo strict waterproof performance testing to ensure that they have reliable waterproof performance at a predetermined level. These tests include water shower, water immersion, pressure test, etc.
In short, the waterproof principle of the waterproof limit travel switch mainly includes the use of waterproof materials, tight shell design, waterproof joints and seals, coatings and other measures, as well as strict waterproof testing. These comprehensive measures make it able to effectively resist liquids Penetration, resulting in reliable waterproofing when working in wet, liquid environments.
