What is the Ignition Switch in a 1966 VW Bug?
Think of the ignition switch as the Bug’s “start button” (old-school style). It’s a vital link between your key, the battery, and the engine. When you turn the key, it sends an electric handshake to the starter motor, saying, “Hey, let’s get rolling!”
Overview and Functionality
In a 1966 VW Bug, the ignition switch powers the starter, manages accessory functions, and ensures your car’s electrical system stays in harmony. It connects your car’s battery to the starter motor with just a twist of the key.
