3*6 Tact Switch With Bracket

1. Housing and bracket materials

Plastic: The housings and brackets of light-touch switches are usually made of plastic materials, such as ABS, PC, PA, LCP (Liquid Crystal Polymer), etc. These plastic materials are lightweight, smooth, cost-effective, and easy to process and mold. These plastic materials have the characteristics of light weight, smooth surface, low cost and easy to process and mold. Among them, ABS plastic has good toughness and mechanical strength, PC plastic is highly transparent and flame retardant, while LCP has excellent heat resistance and electrical properties.

Metal: In some high-end or special application scenarios, the housings and brackets of flick switches may also be made of metal materials, such as stainless steel and aluminum alloy. The metal shell has better heat dissipation, mechanical strength and aesthetics, especially suitable for dustproof, waterproof level of higher requirements of the occasion.

2. Contacts and conductive sheet material

Pure silver/silver alloy: As the core component of the light-contact switch, the choice of material is crucial. Pure silver has excellent electrical conductivity, but weak resistance to sulfidation, easy to form silver sulfide affects the conductive properties. Therefore, many manufacturers will choose silver alloy as the contact material to improve its conductivity and corrosion resistance. Silver alloy contacts have the advantages of low resistance, abrasion-resistant texture, high melting point and oxidation resistance.

Copper and its alloys: In addition to contacts, there are other conductive parts involved inside the flick switch, such as conductive sheets, pins, etc. These parts are usually made of copper and its alloys. These parts are usually made of copper and its alloys due to their good electrical conductivity, mechanical strength and corrosion resistance. In some cases, the surface of these parts will also be gold-plated or silver-plated treatment to improve its conductivity and corrosion resistance.

3. Spring and Shrapnel Materials

Stainless steel: The short trigger stroke of the light-touch switch requires the internal spring and shrapnel to have sufficient elasticity and recovery force. Stainless steel has become the preferred material for the internal spring and shrapnel of the tap changer due to its excellent corrosion resistance and stability.

Phosphor bronze and other alloy materials: In addition to stainless steel, phosphor bronze and other alloy materials are also used in some specific applications of the light touch switch because of its good elasticity and conductivity.

4. Cover plate: The cover plate of the light-contact switch is usually made of metal materials, such as brass, etc. The main function of the cover plate is to protect the contacts. The main role of the cover is to protect the contacts and internal components from the influence of the external environment, and play a certain role in decoration.

5. Pushbutton: The pushbutton part is usually made of the same plastic material as the shell to ensure the consistency of its appearance and the comfort of its hand feeling. In some cases, the surface of the buttons will also undergo special treatment, such as non-slip, wear-resistant and so on.
