Toggle switch components, application scope and precautions of introduction

Toggle switch is a kind of switch that carries out the function of opening and closing by toggling. Generally we use it for the operation of some low-voltage circuits, characterized by its particularly flexible slider and stable performance. In a variety of meters and instruments have a wide range of applications. For example, we commonly have a variety of electric toys, fax machines, audio equipment and medical equipment and so on. Below I will give you a brief introduction about toggle switch component parts and application scope and precautions, I hope you can help.

One, the components of the toggle switch

The toggle switch is mainly assembled by the following components through the corresponding process:

1. Iron shell (material: generally iron; processing: through the electroplating of nickel or potting black process, so as to prevent its oxidation)

2. Plastic handle (material: generally POM material, such as fire-retardant, high temperature requirements, often choose Plastic handle (material: generally POM material, if there is a fire-retardant, flame retardant, high temperature requirements, it is often used PA nylon material processing: injection molding)

3. Terminal (material: generally phosphorus copper; processing: silver plating)

4. Insulation base plate (material: bakelite; processing: stamping)

5. Contact code piece (material: generally phosphorus copper; processing: silver plating)

6. Wave bead (Material: generally stainless steel; Processing: nickel plating)

7. Slingshot (Material: bronze; Processing: stamping molding)

8. Decorative oil (Material: red oil or green oil chemical oil of a kind, coated in the terminal and the base plate of the contact area, play a decorative role. General requirements of non-toxic, environmentally friendly)

Two-Toggle switch applications

1. audio-visual products: MP3, MP4 stereo;

2. digital products: digital cameras, digital camcorders, etc.

3. communication products: cell phones, car phones, telephones, building equipment, PDA, etc.;

4. security products: visual Security products: visual intercom, monitor, etc.

5. Toys: electronic toys, etc.

6. Computer products: camera, etc.

7. Fitness equipment: electronic body fat scale, treadmill, etc.

8. Medical equipment: blood pressure meter, thermometer, hospital call system, etc.

Three, toggle switch precautions

1. careful use of chemicals

Toggle switch base plate because of the use of synthetic resins such as polycarbonate, so should avoid the potentiometer exposed to ammonia, amine, alkali solution, su hydrocarbons, ketones, esters, halogenated hydrocarbons, and other chemicals in the atmosphere of the strong.

2. Use flux with caution

Water-soluble flux should be avoided when soldering, or it will have an adverse effect on the metal and other materials that make up the toggle switch.

3. Soldering

The wiring design and soldering method should be avoided to cause the molten tin to flow to the PC board plane, which will cause poor contact.

4. Low-temperature work

When the product is used in low-temperature environments, such as car radios or car stereos in cold zones, our company provides comfortable products according to customer requirements, please specify when ordering.

5. Slide handle length

The shorter the length, the better (at least 5mm) in the case of the width of the slide handle A unchanged, the shorter the length of the slide handle, the better the feel, and the higher the point of force, the worse the feel.

6. Drive arm

Do not make the operating point away from the centerline of the handle, for the same reason, the shorter the distance B the better.
