- the power semiconductor switch 43 is integrated in the control unit 21 and connected to ground.
- the ignition lock 12 Located in the state shown the ignition lock 12 in the off state.
- the driver brings the ignition switch 14 in a first position (terminal S) in which for example, the car radio is supplied. Subsequently the ignition switch 14 is in the "ignition on” position brought.
- the ignition switch 14 provides an electrical conductive connection between the potential of the battery positive terminal 16 and the ignition contact 24. This is the Ignition terminal 18 at positive potential.
- the control unit 21 evaluates the associated flank change at the ignition contact 18 pending signal from "Off" to "On" off.
- the Control unit 21 also recognizes that - since the ignition switch 14 is not yet in the starting position - the start terminal 20 is not yet at the positive potential of the battery 10 lies. As long as the starting position has not yet been reached, becomes the first switching means 26 in the sense of closing driven.
- the start relief clamp 34 is thus located (Terminal 75) on the positive potential of the battery 10.
- Start relief terminal 34 are such electrical consumers connected, which are activated with "ignition on” such as air conditioning, additional headlights etc. However, to the vehicle electrical system not during of the start-up process, these are Consumer switched off during the starting process.
- a corresponding control command for the first switching means 26 in the sense of opening the control unit 21 gives when the user turns the ignition switch 14 to the start position has moved.
- the start contact 22 is also positive Plus potential, what tapped through the start terminal 20 and the control unit 21 is supplied for evaluation. Also the output potential of the ignition terminal 18 still shows that Plus potential of the battery 10.
