Described circuit board comprises control circuit board and the power supply circuit board that is equipped with control circuit board, and described several LED lamps are located on the control circuit board.

Described face-piece is made by transparent plastic.

Described body is made of plastics, and sprayed coating or electrodeposited coating can be set on its surface.

The beneficial effects of the utility model: key switch of the present utility model is a plurality of conjuncted key switches of tape light that touch, each button periphery when work all has the indication ring of light, and each button can be set have different functions, use circuit board to carry out program control, only need pressing keys will finish the operation requirement of setting automatically during operation, its feel is slim and graceful, and is easy to use, lightly portable, it is little to take up room, and can well cooperate small household appliance to use.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Embodiment

For further setting forth technological means and the decorative effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.

Shown in Fig. 1-8, key switch of the present utility model comprises: face-piece 2, the body 4 that is equipped with face-piece 2 and be contained in circuit board 6 in the face-piece 2, face-piece 2 is made by transparent plastic, be used for fixing body 4 and circuit board 6, and go back transmit light, which is provided with several through holes 22, be provided with the transmittance section 24 of annular around through hole 22; Body 4 comprises several buttons 42, these several buttons 42 are contained in these several through holes 22 respectively and expose this several through holes 22, body 4 is made of plastics, with the convenience that provides the user to operate, and can do surface treatments such as spraying, plating in body 4 surfaces, and go up formation sprayed coating or electrodeposited coating in its surface; Circuit board 6 comprises control circuit board 60 and the power supply circuit board 61 that is equipped with control circuit board 60, control circuit board 60 is provided with several LED lamps 62, these several LED lamps 62 respectively with several button 42 corresponding settings, in addition, also be provided with electronic components (not shown) such as IC (integrated circuit), resistance, electric capacity, winding displacement on the control circuit board 60, control circuit board 60 combines with body 4, face-piece 2 thinks that small household appliance provides operation interface, use as program control, the setting of control circuit board 60 can be passed through existing techniques in realizing; Power supply circuit board 61 is used to provide control circuit board 60 power supplys.

The guidance panel that key switch of the present utility model can be used as small household appliance equipment uses, pressing keys 42, IC control circuit and the LED lamp corresponding on can turn-on control circuit plate 60 with this button of being pushed 42, control program is worked, the LED lamp is luminous, light is projeced on the face-piece 2, make the operator be convenient to operate various electric equipments, and finish corresponding operating.
