1. Field of the Invention
The present invention relates to a handle switch for a vehicle. More particularly to a handle switch for a vehicle including a composite switch which is suitable for operating a navigation display device, etc.
2. Description of Background Art
Heretofore, composite switches have been known that are designed for a reduced layout space and improved operability by having a plurality of operating elements centralized in one place.
Japanese Patent Laid-Open No. 2005-302347 discloses an arrangement wherein a four-way switch is disposed outside of a centrally located push switch and a rotary switch is disposed outside of the four-way switch. Japanese Patent Laid-Open No. 1998-199374 discloses an arrangement wherein a composite switch doubling as a push switch and a four-way switch is disposed centrally and a rotary switch is disposed outside of the composite switch. Japanese Patent Laid-Open No. 2009-4209 discloses an arrangement wherein a composite switch doubling as a four-way switch and a rotary switch is disposed outside of a central push switch.
In recent years, there has been a growing demand for vehicles, not only four-wheeled vehicles but also motorcycles, which have a display device or a navigation device that can be connected to the Internet for browsing the web, and which allow the vehicle occupant to operate the display device or the navigation device while in the riding posture when the vehicle is temporarily stopped. The composite switch disclosed in prior art identified above is suitable for operating those devices. However, since the handle of the motorcycle has switches for operating electric devices including a horn, a headlight, etc., the composite switch needs to be reviewed in terms of its structure and layout if it is to be added and also in view of making itself resistant to erroneous operation.
