What is a slide switch?
The slide switch, also known as the band switch, is a plug-in component of the circuit. Used to switch bands or select different circuits. According to the specifications, it can be divided by the number of knives, the number of bits and the number of layers of insulating sheets; According to the structure, it is divided into toggle type, rotary type, push key type, piano key type and so on.
Introduction to Slide Switches
Band switch is a very old name. In fact, it should be called a multi-knife multi-throw switch, because it can not only be used as a band switch, but also for other purposes. As for how many knives (that is, how many sets of contacts) are needed, it depends on the needs of your circuit. Of course, at least two or more groups can be called band switches. As for how many throws (that is, how many gears) are needed, it also depends on your needs. There are from 2 gears to more than 10 gears. If it is only used as a band switch, there are at least 4 sets of contacts, and at most 6 sets of contacts are enough. In terms of gears, as many bands as there are, you need as many gears, at least 2 gears. There are also various types of “sliding switches”, the common ones are rotary, push-pull, and button (key) type. The size is also large and small.
Classification of slide switches
According to the operation mode, it can be divided into: rotary type, toggle type and lever type, and the rotary switch is usually used more.
Each contact piece of the slide switch is fixed on the insulating substrate.
Insulating substrates typically consist of three materials:
High-frequency porcelain is mainly suitable for high-frequency and ultra-high-frequency circuits. Because its high frequency loss is small, but the price is high;
Epoxy glass cloth glue board, suitable for high frequency circuits and general circuits. Its price is moderate, and it is widely used in ordinary radios and tape recorders;
Paper rubber sheet, its high-frequency performance and insulation performance are not as good as the above two, but the price is low. It is widely used in popular radios, tape recorders and instruments.

The purpose of the slide switch
It is mainly used in radios, tape recorders, televisions and various instruments and meters. It is generally a multi-pole multi-position switch, and each contact piece of it is fixed on an insulating substrate.
The band switch is used in the radio to change the number of turns of the coil connected to the oscillating circuit. The input circuit of the radio is an oscillating circuit composed of an inductor and a capacitor. Discontinuously changing the inductance can change the natural frequency range of the oscillating circuit, that is, changing the receiving band.

one. Precautions for sliding switches in electronic switches
Slide switch is a common electronic switch, its design and use need to pay attention to the following:
Current and voltage: When using a slide switch, you need to pay attention to its rated current and voltage range to avoid damage to the switch due to overload or overvoltage. Different types of slide switches have different current and voltage levels, which need to be selected according to specific applications.
Temperature: The operating temperature range of the slide switch is also a factor to consider. When using a slide switch in a high or low temperature environment, it is necessary to select a model that meets the requirements to ensure its normal operation.
Maintenance and maintenance: After using the slide switch for a long time, there may be poor contact, decreased sensitivity, etc., and cleaning and maintenance are required. It can be restored to normal use with special cleaners or light abrasives.

Second, the functional characteristics of the slide switch in the electronic switch
Slide switches have the following functional characteristics in electronic equipment:
Adjusting circuits: Slide switches are often used to adjust parameters such as current, voltage, and frequency in circuits. For example, in audio equipment, slide switches can be used to adjust functions such as volume and balance.
Switching circuits: Slide switches can also be used to switch circuits, such as switching between different audio sources, switching lights, etc. In electronic equipment, slide switches typically switch faster than rotary switches.
Control Circuits: Slide switches can also be used to switch control circuits. For example, in a power control circuit, a slide switch can be used to control the switching state of the circuit.
Multifunctional Combination: The slide switch can be combined with other switches to achieve multiple functions. For example, in audio equipment, a slide switch can be combined with a rotary switch and a button switch to realize various functions such as volume adjustment and audio source switching.
- Application example of slide switch
Slide switches are widely used in various electronic devices, below we will introduce some common applications:
Mobile phones: Slide switches are widely used in modern mobile phones, such as volume adjustment, mute switch, etc. According to statistics, the global mobile phone shipments in 2020 will be 1.57 billion units, most of which use slide switches.
Laptops: Slide switches are often used in laptops for power and volume control. According to the International Data Corporation (IDC), global notebook computer shipments reached 65.7 million units in the first quarter of 2021.
Audio equipment: Slide switches are widely used in audio equipment, such as stereos, headphones, etc. For example, the Beats Solo3 Wireless headphones use slide switches to adjust volume, answer calls, and more.
Automotive: In automobiles, slide switches are commonly used to control functions such as interior lighting, windows, heated mirrors, etc. According to data from JATO Dynamics, an automotive market research company, global car sales in the first quarter of 2021 will be 17.36 million vehicles.
To sum up, slide switches are widely used in electronic equipment, and their precautions and functional characteristics are of great significance for the selection and use of slide switches.

Rocker switches are also called rocker switches. Its structure is the same as that of the button switch, except that the button handle is changed into a ship shape. Rocker switches are often used as power switches for electronic equipment. Its contacts are divided into several types such as single-pole single-throw and double-pole double-throw, and some switches also have indicator lights.
Rotary Switches, Rotary Limit – Isolator Switches
Rotary switches can be used to replace rotary pulse generators that mimic the function of conventional resistive potentiometers. These rotary switches are commonly used in human-machine interfaces on instrument front panels and audio-visual control panels. A rotary switch uses a quadrature optical encoder as a purely digital device instead of an analog potentiometer.
