What is a negative ion switch?

　　Negative ion switchWe can see from its name that this product is used to do, this product is also after continuous improvement of the function more and more, in order to make more people familiar with it, the next small series for everyone to introduce what is the negative ion switch.

Negative ion switches are interpreted as on and off. It also refers to electronic components that can open circuits, interrupt current, or cause it to flow to other circuits. A very common switch is a manually operated electromechanical device having one or more electrical contacts. The "closing" of the contact means that the electronic contact is turned on and allows current to flow; the "opening" of the switch means that the electronic contact is not turned on to form an open circuit and does not allow current to flow.

To put it simply,Negative ion switchNegative ions can be released in the open state, while negative ions are not released in the closed state. Then we know that negative ions have two functions in people's daily life, purifying the air for health care. According to the research of relevant departments, the small particle size negative ions have the effect of reducing dust and smoke, and are very effective in improving air quality. Moreover, the negative ion particle size is small, easy to pass through the human body's blood-brain barrier, more easily absorbed by the body. So when people live in a space full of negative ions for a long time, it is beneficial to improve people's metabolism, regulate heart function, and enhance the body's ability to resist viruses. Very simple switches have two pieces of metal called "contacts". When the two contacts are in contact, the current forms a loop, and when the two contacts are not in contact, the current is disconnected. Corrosion resistance should be considered when selecting contact metals, because most metals will oxidize to form insulating oxides, which will prevent the contact from working properly. At the same time, the choice of contact metal also needs to consider its conductivity, hardness, mechanical strength, cost and whether it is toxic. Sometimes the contacts are plated with corrosion-resistant metal. Generally, it is plated on the contact surface of the contact so as not to affect its performance due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are also used for the contact surface. In addition to the contacts in the negative ion switch, there will be moving parts to make the contacts conductive or non-conductive. And the switch can be divided into lever switch, key switch, rocker switch and so on according to the different movable parts. At the same time, its movable parts can also be other types of mechanical connecting rods.
