Are you curious about how I often use toggle switches? Where can I use it? The following is a brief introduction to you.
We have to use switches in our daily life. I wonder if you have ever wondered why switches can control household appliances so easily and easily. What is it made of? What areas can switches be used in addition to controlling the lights used in our homes? What should we pay attention to when they are used?
Components of toggle switch
Component 1. Iron shell (material: generally iron; treatment process: through electroplating nickel or blackening process, so as to prevent its oxidation)
Component 2. Plastic handle (material: POM material generally, if fire retardant and high temperature resistant requirements, often choose PA nylon material processing technology: injection molding)
Component 3. terminal (material: generally copper phosphate; processing technology: Silver Plated)
Component 4. insulation base plate (material: electric board; processing technology: stamping molding)
Component part 5. contact chip (material: generally copper phosphate; processing technology: Silver Plated)
The components consist of 6. round beads (material: stainless steel in general; treatment process: nickel plated).
Component part 7. catapult (material: bronze; processing technology: stamping forming)
Component 8. Decorative oil (material: red oil or green oil, a kind of chemical oil, smeared on the terminal and the bottom of the contact area, for decorative effect. General requirements are non-toxic, environmentally friendly.
Introduction of application scope and matters needing attention
Application of the 1. large current sealed toggle switch. The switch has a limited current of up to 5A and is sealed with epoxy resin, as the name suggests. Its appearance is many kinds, generally its contact material has different functions. Usually there are two kinds of silver plating and gold, mainly used in electrical appliances and machinery.
Application area 2. patch type toggle switch. This kind of switch is mounted on the surface, to switch it is generally operated on the side, and the pin is mounted on a chip, which is commonly seen in communications and digital audio and video.
Application range 3. direct acting toggle switch. The name is determined by its contact form, and its pins are plug-in, and its most special feature is that it has two, three, four gear options, but also with a bracket to support the heel fixed, as well as power supply, in building automation and electronic products used more.
Precautions 1. use in electrical rating. If it is used more than rated, it will not only reduce its durability, but also may be dangerous of heating and burning.
Notes 2. Instantaneous voltage and current in the switching on and off, within the range of rated voltage and current.
The switch is a very small object, even if we use it every day, it will still be ignored by us. Believe that the above switching components and switch can be applied to the scope of attention, but also to allow more people to think more deeply about the switch this product.
