This invention relates in general to motor vehicles and more particularly to an interface for controlling operations of a motor vehicle. Most particularly, the invention relates to a switch for motor vehicles.
A conventional interface for a motor vehicle typically includes a switch or switch array, which generally comprises a large number of switches, that are mounted in and around the armrests, console and/or dashboard of the motor vehicle. Some switches are operable to actuate and de-actuate different electrically operated devices. Other switches are commonly referred to as status switches, which are used during certain status conditions of the motor vehicle, such as when a scheduled oil change is due, a low tire pressure condition exists, the motor vehicle trip odometer is activated, or the time clock change function is activated.
Conventional motor vehicle switches are mechanical switches having physically moving (e.g., sliding) parts that create contact between conductors. The switches are supported in openings in a motor vehicle interior trim component. The openings in which the switches are supported commonly attract dust and dirt, which is difficult to reach. Consequently, the interior trim component is difficult to clean. The requirement for openings in motor vehicle interior trim components also requires increased cut lines, leading to increased production time and cost.
The physical characteristics of convention motor vehicle switches usually occupy a space (i.e., usually about 0.5 to 5 mm) for the movement of the mechanical switches. The space limits the ability to style and craft the interior components (e.g., the armrest, console, and/or dashboard) of the motor vehicle. The switches are also subject to wear and mechanical breakdown due to the moving parts and thus may become unreliable. Moreover, the unique character of each switch requires an increased parts count and consequently, increased inventory cost.
Status switches, in particular, are often in obscure locations due to the infrequent use of such switches. The location of some status switches, such as an oil change switch, which is typically in the motor vehicle fuse box, makes it difficult to find and operate the switch. Moreover, since status switches are infrequently used, the motor vehicle manufacturers prefer that the switches not impact the styling of the vehicle.
What is needed is a highly reliable status switch that is easy to use and that does not interfere with the styling of motor vehicle interior trim components.
