Toggle switch The embodiment of the present invention discloses a toggle switch device, which comprises a toggle button, a toggle switch and a housing of an electronic device with a toggle button. The electronic device housing is provided with a mounting hole, corresponding to the mounting hole. The rib is protruded from the inner side wall of the casing, and the rib is provided with a buckle. The toggle key comprises an operation part, a mounting part and a toggle part, and the dial part is open on one side and has a U shape. The utility model improves the uniformity of the matching gap between the toggle key and the nested shell, improves the appearance grade, improves the assembly sequence and the assembly method, improves the assembly efficiency, reduces the cost, and reduces the assembly failure. The rate increases the reliability of the use of the toggle button.
The utility model discloses a toggle switch, which comprises an outer shell and a base cover. The cavity formed by the outer shell and the base cover is provided with a push seat, a contact bridge and a terminal, and the contact bridge is an integrally formed elastic metal contact. bridge. Since the conductive conversion part of the toggle switch provided by the utility model directly uses an elastic metal contact bridge, the original contact bridge and the elastic element are combined into one. The general elastic element is a spring or a spring piece, and the tact switch and the toggle The industry in which the switch is most dependent [toy industry] simplifies the installation process, simplifies the assembly of the cumbersome contact bridges and elastic components in the assembly process, and simplifies the components, thereby reducing material costs and additionally Compared with the structure of the traditional elastic element and the contact bridge, the elastic metal contact bridge of the metal part has the basic principle of the toggle switch, and the structure is more robust, and can withstand repeated use for a long time without being prone to failure or damage.
Also using PC materials, many switch manufacturers use domestically produced products (even if the US GE is actually used by domestic cooperative factories, but only sold by GE), but currently there is no company in China that has the ability to produce PC materials, the so-called domestic production is generally reworked with recycled materials, so the impurities are relatively high, it will be very brittle, and the heat resistance is also obviously poor. Poor switches are used to reduce costs. The front panel may not be populated with PC material and replaced with mix or ABS. These materials are not only resistant to impact and heat, but also prone to discoloration and appear rough when the surface is touched.
Toggle the switch to see the housing material first. The main switch brands in the market generally use PC materials. PC materials are also called bulletproof rubber. The characteristics of impact resistance, high temperature resistance and non-discoloration are very important for controlling electrical switches. The better front panel and the back base are made of PC material, and the general switch will replace the PC material with black nylon material on the base, so the cost can be reduced a lot.
Secondly, the contact is the contact point of the conductive part during the switching process. The size of the contact depends on the size (the bigger the better), the second depends on the material. There are currently three main types of contacts, silver-nickel alloy, silver-cadmium alloy and sterling silver. Silver-nickel alloy is an ideal contact material at present, and its conductivity and hardness are relatively good, and it is not easy to oxidize and rust.
Silver-cadmium alloy contacts are also better in other aspects, but the cadmium is a heavy metal. On the one hand, it is harmful to the human body. On the other hand, the fusion with silver is not ideal. It will form small particles of cadmium metal on the surface of the contact, and conduct electricity. When the arc may be pulled out, the computer basics multiple choice questions.
The contact of sterling silver is not suitable. The conductivity is good, but the texture of sterling silver is soft and it is easy to oxidize (like silver jewelry will turn black after a long time). The texture is soft, the switch is deformed when the switch is more; the oxidation performance is much worse when the oxidation is rusted, the rust point is also prone to heat, and the contact is easily burned.
Toggle switch purchase knowledge
Choosing a good toggle switch has a very important effect on our life. Next, let's talk about what aspects to pay attention to before purchasing the toggle switch: look at the handles with good quality. Most of the switches use high-grade materials such as bulletproof rubber. Made of fire resistance, moisture resistance, anti-collision performance, etc., the surface is smooth, you should consider the feel of your own touch when purchasing, determine the material of the switch by hand, and ask the dealer. In general, products with a surface that is not too smooth and that feels thin and brittle are unreliable. A good switch socket panel requires no air bubbles, no scratches, and no smudging. The touch of the switch is light and not tight, and the socket of the socket needs to be equipped with a protective door. The plug should be inserted and removed with a certain force and cannot be inserted in one foot. Look at the appearance of the toggle switch switch and the surface should look smooth. The plating treatment should also be smooth and bright in the sunlight.
The toggle switch is mainly assembled from the following components through the corresponding process:
1. Iron shell (material: generally iron; treatment process: by electroplating nickel or blackening process to prevent oxidation)
2. Plastic handle (material: generally POM material, if there is fire retardant and high temperature resistance requirements, then PA nylon material processing technology is often used: injection molding)
3. Terminal (material: generally phosphor bronze; treatment process: electroplating silver)
4. Insulation bottom plate (material: electric wood board; processing technology: stamping)
5. Contact chip (material: generally phosphor bronze; treatment process: electroplating silver)
6. Round wave beads (material: generally stainless steel; treatment process: electroplated nickel)
7. Slingshot (Material: Bronze; Process: Stamping)
8. Decorative oil (Material: a kind of red oil or green oil chemical oil, applied to the contact part of the terminal and the bottom plate, plays a decorative role. Generally required non-toxic, environmentally friendly)
