Description

Encoder with dual bit switch function

The invention has a double-bit switch function encoder, which integrates the code and the double bit switch, and can be used as a double-cut linkage switch, and is particularly suitable for being installed in a bathroom and a room to control the light and shade and realize double linkage. control function.

According to the component products that exist for both the encoding function and the switching function, there are currently three forms of use in the market: one is to separate the encoding function and the switching function independently on the two component products, and this form inevitably causes an increase in cost and gives The end user brings inconvenience to the operation.

The other form is to simply assemble the coding function and the switch function, but the coding function and the switch function are respectively controlled by different operation handles, that is, there are two operation handles on the same product. Although the combination of the two functions can be realized, strictly speaking, the distance between the two products in the former form is reduced. And the switch function in this way is the inner handle It is realized by tilting a certain angle, so there is enough gap between the inner and outer operating handles to affect the aesthetic appearance of the product. The structure in which the operating handle is tilted at a certain angle to realize the switching function also causes a bad sense of rhythm during operation, and the rhythm of operation in all directions is difficult to be consistent.

Another one is to combine the coding and switching functions and make the functions independent of each other. For example, the "encoder with eight-way switch" disclosed in Chinese Patent No. CN201010272403.3, the encoder realizes three functions. One is the flat push operation function, the other is the axial operation pressing function, and the third is the rotary operation function.
