When choosing the switch, we should pay attention to the selection of materials, not from the appearance alone. The specific selection methods are described in detail below.
The matters needing attention when selecting the material for toggle switch.
Toggle switch material: including iron shell, electronic, copper strip, dial bead, catapult and so on.
The materials used in the switchboard are excellent in flame retardancy, insulation, impact resistance and moisture proof. The material is stable and not easy to change color. Now the switchboard is made of gold, stainless steel, copper and other metal materials besides high-grade plastics, which provides more and more choices for people.
Two, surface treatment.
Surface smooth, uniform color, texture, is generally a good product, in addition, the brand logo on the panel should be clear, full, the surface can not have any burrs on the switch.
Three, the choice of copper sheet.
1, the thickness of the copper plate will increase the current carrying capacity and reduce the resistance of the copper piece itself.
2. Strong toughness, especially for the switching switch socket part, not easy to deform, even if long-term use, but also maintain the appropriate clamping force, ensure that the socket and plug are closely connected, reduce arc.
3, oxidation resistance, no rust, reduce the corrosion resistance caused by corrosion and heating problems.
4, less riveting, preferably a piece of copper, further reduce the riveting part fracture and rivet heat.
The key switch is an electronic switch, which belongs to the category of electronic components. This kind of switch first appeared in Japan. The toggle switch is called the sensitive switch. The main type of the key switch refers to the light touch key switch, which is commonly referred to as the light touch switch. The working principle of the key switch depends on its internal structure. When using, we apply pressure and pressure to switch operation direction to make the switch function close and close. When we want to disconnect the switch, we only need to remove the pressure. The key switch mainly consists of five parts: insert, base, shrapnel, button and cover plate.
There are many kinds of button switches, which can be divided into two main categories: the first one is to use metal reeds as contact plates. This kind of switch has small contact resistance and good handle. The second one is to use conductive rubber as contact path. This kind of switch has small contact resistance. When we choose the switch, we should use conductive rubber as contact path. We must not choose to follow suit blindly. We need to choose the right switch according to our actual situation.
There are many advantages of button switch, such as small contact resistance charge, precise operating force error, diversified specifications, etc., so its application scope is also very wide, mainly used in electronic equipment and white household appliances, such as: audio and video products, digital products, remote control, communication products, household appliances, security products, toys. Computer products, fitness equipment, medical equipment, money detector pen, laser pen buttons and so on.
