Lincoln Navigator Ignition Switch

The switch is part of the ignition/charging system in Lincoln Navigator cars, this system is chargeable with the function of turning the engine on as well as powering all electrical parts within the automobile like radio, power windows among others. With the help of Ignition Switch key, button or remote, turning the switch the computer recognizes a command to turn on the starter solenoid and ignition components to start the vehicles' engine. There are also differences in styles of Ignition Switches, where the early models of Lincoln Navigator had used usual mechanical keys that are inserted into the switch while the more recent models indicate the use of push buttons.
