What points should be paid attention to in the selection method of the water-proof switch? We will give you detailed details below.
What is a water-proof switch? To put it plainly, it is a switch that can be washed in water or rain without failing. Usually the waterproof switch level is IP67, which can completely protect the dust in the air. At the same time, it can operate steadily in the position of about 1 meter underwater. At room temperature, it will not be damaged for about 30 minutes. Today, Xiaobian shares with you the knack of selecting a water-proof switch.
1. Waterproof grade IP67
The two digits behind IP represent the protection from large particles of foreign matter to dust and from vertical water droplets to water pressure. The larger the two digits behind IP, the stronger the ability to express.
2. Attention should be paid to working temperature
The jitter and oscillation specified by the type of switching switch set the circuit as a combination component without misoperation, so it can not be used for a long time near the upper limit and lower limit of the temperature range.
3. Careful use of water soluble flux
Water soluble flux may corrode the trigger switch when welding the switch, so try not to use it. If the pressure is applied on the switch, it may cause the switch to be loose and deformed, so we should pay attention to it when welding.
4. Voltage also needs attention
If the water-proof switch is used under the rated voltage, it will cause bad contact. When using the switch, it should meet the requirements of the product specification and be within the range of various environmental tests in the parameter book.
Waterproof switch is widely used in small household appliances, game consoles, digital cameras, remote controllers, keyboards, bathrooms and other products. People's pursuit of life is getting higher and higher, and the performance and appearance design of many products are also getting higher and higher. Waterproof toggle switch is small in size, but it controls the operation and stop of the whole product. It also brings customers the most intuitive product experience, so the quality of waterproof toggle switch has a great impact on product quality. This is the manufacturer friends need to pay attention to the issue of purchase.
