What are the components of the switch and the scope of its use? We will give you a detailed description of the details below.
In our daily life, we need to use switches. I wonder if you have ever thought about why switches can be so simple and easy to control household appliances. What constitutes them? What areas can switches be used in addition to controlling the lights used in our homes? What should we pay attention to when using them?
Components of a toggle switch
Component 1. Iron shell (material: generally iron; treatment process: by electroplating nickel or pot black process to prevent its oxidation)
Component 2. Plastic handle (material: POM material generally, if there is fire retardant, flame retardant and high temperature requirements, PA nylon material treatment process: injection molding)
Component 3. Terminals (Material: generally phosphorus-copper; Processing: Silver plating)
Component 4. Insulation floor (material: bakelite; processing technology: stamping)
Component 5. Contact chip (material: generally phosphorus copper; treatment process: silver plating)
Component 6. Circular beads (material: stainless steel; treatment process: nickel plating)
Component 7. Slingshot (Material: Bronze; Processing: Stamping)
Component 8. Decorative oil (material: a kind of red or green oil chemical oil, which is applied to the contact part between terminal and base plate, playing a decorative role. General requirements non-toxic, environmental protection)
Introduction of Application Scope and Notices
Scope of application 1. Sealed switch with large current. This kind of switch has a limited current, its current can only be 5A at most, and it should be sealed with epoxy resin, which can be seen from the name. It has many shapes, and its contact materials generally have different functions. Usually there are two kinds of silver plating and gold plating, mainly used in electrical and mechanical.
Scope of application 2. Patch-type toggle switch. This kind of switch is mounted on the surface. If it is to be switched, it is usually operated side by side, and the pins are patched. This kind of switch is commonly seen in communication and digital audio and video.
Scope of application 3. Directly inserted toggle switch. This name is determined by its contact form, and its pins are straight-in type, and its most special is that it has two, three, four gear selection, but also with brackets, used to support and fix, as well as access to electricity, in building automation and electronic products are used more.
Cautions 1. Use within the electrical rating. Exceeding rated electrical use will not only reduce its durability, but also possibly cause fever and burn damage.
Note 2. Instantaneous voltage and current at the time of opening and closing shall be used within the range of rated voltage and current.
Switch is a very small thing, even if we use it every day, it will still be ignored by us. I believe that the above information about the components of the switch and the scope of its application and the matters needing attention can also make more people think deeply about the switch product.
