Embodiment
Core of the present utility model provides the polymorphic switch of a kind of backlight type.This switch has the sub-light source of a plurality of different glow colors, corresponds respectively to different gears, and according to different display effects, the driver can get information about current mode of operation, is convenient to operate at night.
In order to make those skilled in the art person understand better the utility model scheme, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The term that relates to expression orientation such as " upper and lower " herein is based on the position relationship of accompanying drawing, and terms such as " first, second " only is for convenience of description, has the different building blocks of same names with differentiation.
Please refer to Fig. 1, Fig. 1 provides the structural representation of a kind of embodiment of the polymorphic switch of backlight type for the utility model.
In a kind of embodiment, the polymorphic switch of backlight type provided by the utility model, in order to control engine zero load, underloading, fully loaded between transformation working pattern, mainly consisted of by knob 1 and switch base 2, knob 1 below embeds back light.
Back light comprises three sub-light sources that have respectively different glow colors, wherein the first sub-light source 3-1 is blue-light source, the second sub-light source 3-2 is green light source, and the 3rd sub-light source 3-3 is red light source, corresponds respectively to zero load, underloading, the fully loaded mode of operation of engine.
Knob 1 is provided with the sign position 1-1 of printing opacity, switch base 2 is provided with the printing opacity display area 2-1 corresponding to different gears, the main part of knob 1 and switch base 2 is black shading plastics, and its sign position 1-1 and printing opacity display area 2-1 are white light-passing plastic.
Please refer to Fig. 2, Fig. 2 is the circuit theory diagrams of the sub-light source of the polymorphic switch of backlight type shown in Figure 1.
