Seemingly unrelated to us, the key switch has been accompanied by our life for countless days and nights. Household appliances, digital products, automobiles, agricultural machinery and other fields actually have their small shadow. Facing hundreds of key switches on the market, how do we choose?



Key switch, safety first



Small switch, great function, key switch is such an object. Therefore, when selecting the key switch, safety should be the primary consideration. Once the safety factor of the key switch we choose is not high, it will lead to production stagnation and economic loss in production; In life, it will threaten our life safety. The key switch shall be selected from the aspects of material and heat resistance, so as to improve the safety as much as possible.



Material affects quality



Most of the key switches on the market are made of high-quality PC, because this material has excellent temperature resistance, flame retardancy and impact resistance. The key switch may have tens of thousands of operations in use. This material can largely avoid aging caused by high temperature and wear, so as to prolong the service life of the switch. Moreover, the electrical resistance of PC material also allows it to effectively prevent leakage and ensure safety. At the same time, quality is also the basis of good brand reputation.



Structure, see the true chapter for details



Although the key switch is just a small part, the structure is also very important to it. Now the key switches commonly seen in the market are separated structures. The higher the coincidence between the structures, the better the stability of the key switch. In this way, there is no need to worry about poor contact of the switch in use, which will affect the service life~
