Toggle switch and touch switch are the control switches we often use in the circuit to control all kinds of actions and actions. At this time, we can easily make electronic products achieve the desired requirements, and let toggle switch and touch switch easily integrate into the circuit.
Turn switch, touch switch - --- is an electronic switch. When using it, press the switch button quietly to make the switch on. When the switch is released, the switch is off. Its internal structure depends on the force and elasticity of the metal shrapnel to complete the on-off. Micro-switch is widely used in household appliances because of its small size and light weight, such as color TV buttons, DVD machine buttons, computer mouse and so on. However, the micro switch also has its shortcomings. Frequent pressing will make the metal shrapnel lose elasticity and become ineffective due to fatigue. So now most electric buttons are replaced by conductive rubber, such as computer keyboards, remote controllers and so on.
It can also be used to control low-power household appliances such as lighting lamps and exhaust fans. The electronic switch will not be self-connected when it automatically disconnects and calls again after power failure in the city.
How to distinguish the quality of light touch switch with lamp? The general good products with light touch switch have smooth appearance, no burr, bright color and high quality ABS + PC material. They have excellent flame retardant function and are not easy to break. Some products have a smooth surface and seem to be coated with oil, but their color is pale and texture is rough. The flame retardancy of this kind of material is not good enough. You can try its flame retardancy by igniting it with fire. If the light goes out quickly, it's good plastic, otherwise it's bad plastic.
The basic characteristics of light touch switch include:
1. Two models of luminous and non-luminous are available for you to choose.
2. Mould the embedded terminal to avoid the invasion of flux, solution and other impurities.
3. Pressing terminal ensures that PC device is firm and reliable, and avoids displacement during welding.
4. Touch switch series: 4X4X1.5, 4X4X1.6, 4X4X1.7 Note: Copper head, white plastic head for customers to choose;
5. With bracket and square head. Handle color: black, red, white, green, blue, yellow, brown and other special tones;
6, 6X6 series handle heights H = 4.3, 5, 5.5, 6, 7, 7.3, 8, 9, 9.5, 10, 11, 12, 13, 15, 17, 21 and other special heights.
Light touch switch with lamp has excellent conductive function: the circuit with light touch switch can be printed with carbon slurry, silver slurry, copper and platinum, and the conductive layer can be folded at will; and the resistance can be controlled in any resistance you want, moreover, with the unique skills of vibration switch, the film switch can even accept hundreds of thousands of volts of high voltage without damaging its function. Light touch switch with lamp has low cost: some thin film switch sells for only a few cents. Compared with an electronic original device product with so many functions, its price advantage is not as good as other similar products and DC sockets.
The characteristics and usage requirements of these switch types are all what we need, and also the key understanding before installation.
