Raising the comfort for the driver of a vehicle has always been a high priority for the vehicle constructor. The concept of positioning regularly used switches and safety elements on the steering wheel is the aim of this endeavour. Originally the regulators for the accelerator and the ignition timing were positioned next to the horn contact, today in addition to the horn we find levers and buttons for the headlights, turn signals, cruise control system, radio, telephone, CD player etc. Apart from this, the steering wheel contains functional elements such as the airbag and, under certain conditions, a vibration damper. Such a versatile steering wheel is known as a multi-function steering wheel (MFW).

Introduction At the moment the driver must remove his hand from the steering wheel, or even take their eye off the road ahead, to adjust the volume of a radio, select another radio station or to operate the cassette/CD player. The driver’s attention is distracted from the road ahead and therefore dangerous situations may be recognised too late, or even provoked.

Telephoning in the vehicle, whilst driving, creates an even more critical situation. With some hands-free systems the handset must be held in the hand to dial or send a telephone number. Even the use of speed-dial functions may severely distract a driver.
To reduce these moments of danger and to increase the convenience factor still further, some of the regularly used functions for – the radio, – the cruise control system (CCS) – and the operation of the telephone have been integrated into the rocker switches in the steering wheel. Such an equipped steering wheel is known as a Multi-function steering wheel (MFW).

The electrical connections between the steering wheel electronics and the onboard supply is established via a coil connector in the steering wheel.
