　　First, to explain the definition of a multi-way switch, multiple switches in multi-channel data transmission process, according to which any way you need to select a circuit, called a data selector, also known multiplexer. Today'll tell multiplexer switches and multiplexers role category.

　　Multiplexer has 4-to-1 data selector, 8-to-1 data selector, 16-to-1 selector and other points. Multiplexer switch further comprises a bus multiplexer, analog multiplexer selection, the corresponding devices also have different characteristics and use.
　　MUX is a Jiechayuanjian circuit. Used to convert the band or the option of connecting different circuit. According to specifications, the number of knife, the median number of layers and the insulating sheet to points; according to the structure is divided toggle, rotary, push-button, key-type and so on.
　　Band switch, in fact, should be called multi-multi-throw switch knife, because it not only do band switch, can do other uses. As for how much knife (that is how many sets of contacts), to see the needs of the circuit. Of course, at least two or more, to be called the band switch. As for how much needs to throw (that is, how many stalls), but also according to your needs. From 2 to more than eight-speed gear they have. If only for the band switch, a minimum of 4 sets of contacts, up to six sets of contacts is sufficient. Stalls is how many bands, how much gear you need at least 2 files. "Swing switch" of the type also diverse, it is common rotary, there are push-pull, as well as the key (key) formula. Volume also of different sizes.
　　MUX classification
　　By mode of operation can be divided into: rotary, toggle lever type and, more generally applied a rotary switch. Each band switch contacts are mounted on the insulating substrate. Insulating substrate is generally composed of three materials: high-frequency porcelain, mainly adapted to high-frequency and ultra-high-frequency circuits, high-frequency loss because of its small, but the price is high; epoxy glass cloth sheet, suitable for high frequency circuits and general circuit affordable, ordinary radio and tape recorders in many applications; a paper sheet, its high-frequency performance and insulating properties and are not above two, but the low price, the popularity of radio, tape recorders and the application of more instruments many.
　　Multiplexer uses
　　It is in the input circuit is an oscillating circuit composed of inductance and capacitance, the inductance change discontinuously can change the natural frequency range of the oscillation circuit, that is, changing the reception band.
