Brake Pedal misery

The Brake pedal is not coming up all the way and turning off the brake lights causing the battery to die . I had the same problem with my wife's Pathfinder just last year . I checked it by pulling up the pedal with my hand ,the lights go out . Does anyone here know what the name of the part that makes the pedal turn off the lights ? I believe the it was a grommet when the mechanic fixed that nissan .

 

I think it's called the stop lamp switch

 

Thank You

 

Just why is the pedal hanging up??

That seems more of the problem then a stuck brake light switch.
