Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
203 words
In an electrical system for an automotive vehicle having a battery, ignition means, head lamps and parking lamps together with a light switch having an off position, a parking lamp activating position and a head lamp activating position, said light switch having a movable contactor and first and and second pairs of fixed contacts respectively for said parking lamp activating position and said head lamp activating position, a first wiring connection to said first fixed contacts between said battery and said parking lamps, and a second wiring connection to said second fixed contacts between said battery and said head lamps, the combination therewith of further switching means having fixed contact means connected in an operative path between said battery and said head lamps for energizing and deenergizing the same, said further switching means having a second active portion operable to close said fixed contact means, said first wiring connection for said parking lamps bypassing the path including said further switching means, so that when said light switch is in said parking lamp activating position and said active switch portion is actuated to close said movable contact means, the headlamps are energized even though the light switch is in the parking light activating position.
