Is the Micro Switch Waterproof？

Micro switch is a type of switch that is widely used in all fields of life, and it is also needed to be used in many environments, such as damp environment. The above requires that the micro switch quality must have the ability to resist this type of waterproof. The fact is that not all micro switches are waterproof, but as technology continues to advance, some level of waterproof capability is attached to most micro switches. This impermeability is indispensable in many concrete uses, particularly in humid or humidity locations.

How microswitch works to be waterproof?

There are various methods to achieve waterproofing for micro switches, and generally, some common waterproof methods can be mentioned like the sealing design on the surface, applying of the waterproof coatings, using waterproof materials and adopting the special structural design as well... and of course, each way also has its specific characteristic.

• Seal design: Seal design is one of the most popular method micro switches, we could seal the micro switch well on the face make sure no moisture could get inside of the heavy and contact area. Sealing effect is realized with rubber seals, rubber stoppers, or silicone seals, and so on.
• Waterproof coating: A waterproof coating can be applied to the micro switch outer surface or to the circuit board inside, in a way to prevent the interior from being entered by moisture. The coatings in question are typically waterproof, as well as corrosion-resistant and insulating, all of which work to keep the microswitch's internal circuitry safe.
•  Select a waterproof material: For the shell and internal components of micro switch, consider water-resistant resin for example, the coating of microswitch and connecting components are all made of varnish or waterproof plastic, or metal.
• This special structural design, led to the micro switch to get waterproof. However, the most popular is the design of tilted push button to avoid to let some moisture entering the interior of micro switch to have extended service life.

In summary, through the above frequently applied ways, the waterproof of the micro switch can be significantly improved, so that even if it is often used in wet places or with water, the switch can normally work.

Application of Waterproof Micro Switches

Waterproof micro switch is not only used in a variety of applications, in many industries, such as auto, outdoor electronics, household appliances, even in industrial equipment, it can be used, its important significance is self-evident.

•  Automotive electronic equipment:Window switch, door switch, light switch, wiper switch and seat adjustment system and other various control systems are all using these water proof micro switch. Certain systems in cars need to work all the time because they too much for the cars to function properly so waterproof micro switches were designed to be able to protect these devices and still manage to work in rainy environment.
• Because the electronic products you use are not just used at home, they will have outdoor products such as outdoor flashlights, wireless remote controls, smart watches, etc., which must be waterproof after being taken to the outdoor, so that it can be guaranteed in rainy and hot Shanghai when the device will never be packaged because of quality problems.
• Home appliances: Micro waterproof switch can help household machines like washing machine, dishwasher, electric kettle to work stably, safely and durably, as these appliances may in touch with the water or moisture.
• Industrial equipment: in the production process of Industry, some machinery and automation systems need to run in a damp or dusty environment, so the waterproof micro switch can make such equipment switch function still reliable in complex environments.

Advantages of Waterproof Micro Switches

However, some of the more common advantages of using a waterproof basic switch include:

• Enhance product reliability: Waterproof Micro Switch can avoid the entering of moisture and moisture into the equipment, which will lower the rate of the equipment failure in the humid environment and upgrade the reliability and stability of the product.
•  Product life extension: Waterproof micro switch can prevent the wetness, other liquids caused by the corrosion of the internal parts of the equipment, the product life expectancy.
