The brake light switch is at the master cylinder... you might have two switches.
The switches are either 2 or 3 wire switches, which do you have?
With the key on, check for power at one of the wires at each switch.
If you haveo 2 wire switches, simply bridge across the wires and see if the brake lights come on.
If the lights now come on, you have a faulty pressure switch.
