Abstract

A steering wheel switch comprises two sets of switching devices which are in circuit connection through an intercommunicating wire harness. A plurality of functional buttons and corresponding control circuit boards are arranged inside the housing of each switching device. Conductive rubber is arranged inside each housing. Each functional button electrically contacts the corresponding control circuit board in a contact elastic opening/closing way through the conductive rubber. The steering wheel switch has a reasonable structure. The two separate switching devices are in circuit connection through the intercommunicating wire harness. Each functional button can be flexibly arranged according to demands. The conductive rubber serves as the opening/closing conducting medium between each functional button and the corresponding control circuit board. The switch structure is greatly simplified. The product is made compact and small. Opening/closing interference of each button can be prevented. Furthermore, the steering wheel switch which achieves sensitive touches is not easily affected by moisture and dust and has very reliable performance. Comfortable hand feelings of pressing and prodding operations can be further achieved. Meanwhile, the operations are safe.

Description

Steering wheel switch

Technical field: the utility model relates to the function control switch using on a kind of switching device, particularly vehicle steering.

Background technology: function control switch is generally all installed on vehicle steering, makes driver realize various functions at steering wheel direct control.Due to steering wheel switch integrated a plurality of function buttons, general internal structure is more complicated, produces assembling trouble, each button may interfere with each other the switching contact structures of control circuit board, and presses that to stir the feel of operation poor, easily misoperation.

Summary of the invention: for the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, the steering wheel switch of dependable performance.

The utility model comprises the two cover switching devices that connect by an intercommunication wire harness circuit, in the housing of every suit switching device, be provided with several function buttons and corresponding control circuit board, in each housing, be equipped with conductive rubber, each function button is opened and closed and is electrically contacted by conductive rubber and corresponding control circuit plate contact elasticity.

Of the present utility model rational in infrastructure, utilize an intercommunication wire harness circuit to connect two separated switching devices, each function button is flexible topology position as required, and the switching transmitting medium using conductive rubber as function button and between control circuit board, has simplified switch structure greatly, make product compactness small and exquisite, avoid the switching of each button to disturb, and touched sensitively, be not subject to the impact of steam, dust, performance is very reliable, presses the comfortable feel safety of stirring operation.

Below in conjunction with drawings and Examples, further illustrate the utility model.

Accompanying drawing explanation: Fig. 1 is the main schematic diagram of embodiment.

Fig. 2 is the A-A section enlarged diagram in Fig. 1.

Fig. 3 is the B-B section enlarged diagram in Fig. 1.

Embodiment: as shown in Figure 1, two cover switching devices connect by intercommunication wire harness 4 circuit, in the housing 1 of every suit switching device, be provided with several function buttons 2 and corresponding control circuit board 3, in each housing 1, be equipped with conductive rubber 5, each function button 2 is opened and closed and is electrically contacted by conductive rubber 5 and corresponding control circuit board 3 contact elasticity.Two separated switching devices are flexible topology position as required, and wiring simplifies clearly, and the control operation of each button is very convenient.Conventionally the surface plate of housing 1 is Demountable, safeguards and changes conveniently like this.

Each function button 2 parts in the present embodiment are seesaw type buttons, and part is direct press type button.Seesaw type button arranged beneath has 5 touchings of push rod 6 and conductive rubber to coordinate, and the lower end of direct press type button directly and conductive rubber 5 touching cooperations.

As shown in Figure 2 be direct press type button, while pressing this function button 2, conductive rubber 5 also by lower by producing elastic deformation, the corresponding control contact of contact turn-on control circuit plate 3, realizes this control function.As shown in Figure 3 be seesaw type button, can press conductive rubber 56 times, the corresponding control contact of turn-on control circuit plate 3 by push rod.After removing by the external force being pressed on function button 2, conductive rubber 5 elasticity are recovered, and contact disengages, and this functional switch disconnects.

The shape of two housings 1 of the present embodiment is symmetrical, and the function button 2 on surface is also symmetrical arranged separately, forms symmetrical formula switching device.More attractive in appearance while installing and using like this, layout is also reasonable.
