Where is the break light switch 1947 desoto?
The brake light switch is mounted in a brake line junction where a main line from the master cylinder connects to a fitting that branches out to the left and right front brakes. This is located just behind the radiator below the battery. It is not a mechanical switch like you would find under the dash on a more modern car, but it is triggered by pressure from the hydraulic brake lines. If you have a leak, air in the lines, or worn brake shoes you might have difficulty with the switch lighting the brake light.

Don't know when this was asked, but you can ask more from me anytime.
