How to choose the material and what kind of material should be used for the three-stage switch, we will give you a detailed introduction.
With the continuous progress of human science and technology, no matter in industrial production, or in daily electronic equipment, every product research and development results, are inseparable from the switch, switch types are many, commonly seen button switch, micro-switch, and touch the switch, no matter which switch, in their own widely used areas, hair. Playing a pivotal role, today we will introduce a new type of switch, switching, although daily life, we will often see, but as for its working principle, very few people to understand.
The three-stage switching switch is a kind of switching circuit by the action of the switching command acting on the switch handle to make the circuit turn on or off, so as to achieve the purpose of switching circuit. Now the switching switch commonly used types are 12T, 1P3T, 2 switching P2T, 2P3T, and unipolar two-bit, unipolar three-bit, bipolar two-bit and so on, mainly used in low-voltage circuits. It is different from other switches, flexible, stable and reliable features, the most common such as digital cameras, as well as beauty salons popular equipment, the control circuit switch is mainly to switch, children play electric toys, depending on the switch to ensure stability and safety.
How to measure the working performance and working principle of the 2P2T two-speed switch? Through solderability test, the top of the switch terminal can be immersed in the solder pool at a depth of 1_, the temperature is set at 230 degrees, the time is 3 seconds, or less than 3 seconds, and the welding area should reach more than 80%. The measured results must satisfy the requirement that the three-dimensional switch does not deform. After the mechanical and electrical energy of the switchgear is switched, the service life test is carried out without any load. The operator has to do 100000 no-load tests at the frequency of 60 times per minute. Only when each test meets the quality standard can it be considered successful. After reading the above explanation of the switchgear, the working principle of the switchgear has a concrete impression.
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 switch are excellent in flame retardancy, insulation, impact resistance and moisture proof. The material is stable and not easy to change color. Now the switch panel is made of high-grade plastic, but also gold-plated, stainless steel, copper and other metal materials, providing people with more and more choices to switch.
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, no surface burrs.
Three, the choice of copper sheet.
1, the thickness of the copper plate will increase the current passing capability and reduce the resistance of the copper piece itself.
2. Strong toughness, especially when applied to the socket of the switch, it is not easy to deform. Even if used for a long time, it can maintain the appropriate clamping force, ensure that the socket is tightly connected with the plug and reduce the 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 of the fracture and rivet heat.
