Tactile switch is a common electronic component, and its main function is to control the on/off of the circuit.
It is widely used in various electronic devices and household items, such as TVs, stereos, lamps, etc.
While tactile switches differ in form and function, their basic principles are all similar.
1. The principle of the tact switch: The working principle of the tact switch is based on the on/off of the current.
Generally speaking, a tactile switch consists of a switching mechanism, a contact and a base, etc.
When we gently press the switch, the switching mechanism triggers the internal rubber or metal sheet to create a displacement, causing the contacts to touch each other or leave.
When the contacts are in contact, the current is passed through and the circuit is closed;
When the contact leaves, the current is disconnected and the circuit is disconnected.
2. Classification of tactile switchesAccording to different use scenarios and appearance designs, tact switches can be divided into many types.
For example, there are commonly used manual tactile switches that turn electrical equipment on or off with the push of a finger;
There are also inductive tactile switches, which can be controlled by human proximity switches;
In addition, there are LED tactile switches with illuminated effects that provide convenient use at night.
3. Advantages of tactile switchesCompared with traditional mechanical switches, tact switches have many advantages.
The tact switch is light to operate, and users can control electrical equipment with a light touch, making it more convenient and faster to use.
The tactile switch has a long lifespan, generally reaching tens of thousands of press life, so it can work stably for a long time.
In addition, the design of tactile switches is diverse, and it can meet the needs of various products.
4. The application of tact switch in product designThe tact switch is not only a simple switch, but also can add a lot of functions and features to the product.
For example, on the TV remote control, the tact switch can not only be used to control the power switch, but also realize the function of channel switching, volume adjustment and so on by designing different buttons.
On smart speakers, in addition to being used to turn on the device, the touch switch can also be combined with a voice assistant to achieve advanced functions such as voice control.
In addition to the expansion of product functions, the appearance design of the tact switch can also add a touch of beauty to the product.
By using different materials, colors and shapes, tactile switches can make products more stylish and personalized.
For example, some high-end audio products use mirror glass and LED backlight design tactile switches, which make the whole product look more sophisticated and high-end.
In general, as a common electronic component, the tactile switch has the advantages of simplicity, stability and durability.
In product design, tactile switches not only provide basic circuit on/off functions, but also can add more functionality and aesthetics to the product.
In the future, with the development of science and technology, tactile switches will continue to play an important role in various fields.
