Selector switch circuit for disabling an airbag
First Claim
1. A selector switch system for disabling an airbag of a motor vehicle, comprising:
- an electrical power source having a supply terminal and a return terminal;
a switch connected to the supply terminal of said power source;
a first circuit path connected to said switch for activating the airbag, said first circuit path having an airbag device; and
a second circuit path connected to said switch for preventing activation of the airbag;
said switch selectively movable between an enabled position for enabling the airbag device by interconnecting the supply terminal of said power source to said first circuit path, and a disabled position for preventing activation of said airbag device by interconnecting the supply terminal of said power source to said second circuit path, whereby the supply terminal of said power source does not connect to said first circuit path in the disabled position.

Abstract
An airbag control system is provided to disable an airbag in a motor vehicle. The airbag control system includes an airbag control module, a switching circuit with a first circuit path and a second circuit path, and a switch selectively movable between an enabled position, which interconnects the first circuit path to the airbag control module to activate the airbag, and a disabled position, which interconnects the second circuit path to the airbag control module to prevent activation of the airbag. In addition, the system includes a third circuit path with a first resistor in series with a second resistor which is placed in parallel with a second contact of said switch. Alternatively, a controller is electrically connected through the third circuit path to the switch. The controller detects the position of the switch based on the resistance value it senses in the third circuit path. A visual indicator is optionally connected to the controller, whereby selectively moving the switch to the disabled position sends a signal from the controller to illuminate the visual indicator.
