Matters needing attention when using 6x6 tact switch
Waterproof tact switch, as the name implies, is a switch that can be immersed in water or rain without malfunctioning. Generally, the waterproof switch is rated IP67, which can completely protect against dust in the air. At the same time, it can operate stably at a position of about 1 meter underwater, and will not be damaged for about 30 minutes at room temperature. Today I will share with you the tips for choosing waterproof tact switches.
one. Waterproof grade IP67. The two digits behind IP represent protection from large particles of foreign matter to dust and protection from vertical water droplets to bottom pressure. The larger the two digits behind IP, the stronger the capability.
two. Pay attention to the working temperature. The bounce and oscillation specified by the type of the touch switch set the circuit so that the combined components will not cause malfunctions, so it cannot be used for a long time near the upper and lower limits of the operating temperature range.
three. Use water-soluble flux with caution. When soldering the tact switch, water-soluble flux may corrode the tact switch, so try not to use it. If pressure is applied to the switch, it may cause the switch to loosen and deform, so be very careful when welding.
Four. The voltage also needs attention. If the waterproof tact switch is used at a voltage exceeding the rated voltage, it will cause poor contact. When using the tact switch, it should be in accordance with the requirements in the product specification and within the scope of various environmental tests in the parameter book.
Waterproof tact switches are widely used in small household appliances, game consoles, digital cameras, remote controls, keyboards, sanitary ware and other products. People's pursuit of life is getting higher and higher, and the performance and appearance design of many products are getting higher and higher. Although the size of the waterproof tact switch is small, the parts that control the operation and stop of the entire product also give customers the most intuitive product experience. Therefore, the quality of the waterproof tact switch has a great influence on the product quality. This is a problem that manufacturers and friends need to pay attention to when buying
