How to distinguish the quality of illuminated tactile switches from Dongguan? Generally, good Dongguan illuminated tactile switches have a smooth, burr-free appearance, a bright color, and are made of high-quality ABS+PC material, offering good flame retardancy and resistance to breakage. Some products may have a smooth surface, seemingly coated with oil, but the color is pale and the texture is coarse. Such materials have poor flame retardancy. You can test their flame retardancy by lighting a flame. If it ignites and extinguishes quickly, it's good plastic; otherwise, it's very poor plastic.
The basic characteristics of Dongguan illuminated touch switches include:
1. Two models are available: one with light and one without.
2. Molded embedded terminals prevent flux, solution, and other impurities from entering;
3. Crimp terminals ensure the PC is securely and reliably installed, preventing displacement during welding;
4. Dongguan Tactile Switch Series: 4X4X1.5, 4X4X1.6, 4X4X1.7 Note: Copper head and white plastic head are available for customers to choose from;
5. Includes a stand and a square head. Handle colors include: black, red, white, green, blue, yellow, brown, and other special color options.
6. The 6X6 series handles have special heights H=4.3, 5, 5.5, 6, 7, 7.3, 8, 9, 9.5, 10, 11, 12, 13, 15, 17, 21, etc.
Dongguan illuminated tactile switches boast excellent conductivity: the circuitry of these switches can be printed using carbon paste, silver paste, copper foil, etc., and the conductive layer can be folded freely. Furthermore, the resistance can be controlled to any desired level. Utilizing vibration switch technology, the resulting membrane switches can even withstand high-voltage shocks of hundreds of thousands of volts without damage. Dongguan illuminated tactile switches are also cost-effective: some membrane switches cost only a few cents. For such a multifunctional electronic component, their price advantage is unmatched by other similar products, especially DC sockets.
