1994 Honda Civic Stop Switch For Brake Lights

Electrical problem
1994 Honda Civic 4 cyl Two Wheel Drive Automatic

Apparently the stop switch for my brake lights has been broken for a period of time, and this has drained my car battery. Does this mean that the brake lights would have always been on even when the engine was turned off? I don't recall seeing them on after I would park my car. Would this be enough to completely drain my battery?

Thanks
Chris
