I would just remove it and place an ohm meter across the 2 terminals on the switch then move the stalk to and fro to see if it is switching. You'll also see the adjustment screw on the back when you have it off. Be careful not to install it with that stalk on the wrong side of the brake tab or you will break it when you step on it.

Wait 'till night time, insert key in ignition switch, turn to first detent, depress brake pedal, look in rear view mirror ... if you see a red aurora, they work

First check that the brake lights are coming on. Ignition to on. You can use a pole to depress the pedal wedged against the seat if you dont have a helper to check the lights.
The switch is in the depressed position with the pedal NOT depressed.
Adjustment is done my loosening the jam 7mm nut on the slotted screw.
Near Impossible to do with the switch installed. Turning the screw clockwise makes the lights come on sooner. I adjust them so that the lights com on when the pedal moves about an inch.

Trying to figure out if this is a different question from your previous thread?

I'll reiterate that I found it a lot easier to remove the switch to adjust it. Much easier to take it on and off than to try and reach the adjustment screw and lock nut when it is mounted in place. Placement of the lever and washer is also a bit counterintuitive. Refer back to your previous thread for a helpful picture. A previous owner may have tried to adjust the switch by bending the lever so be aware that you might need to correct that.

Most replacement switches are so far are of adjustment they will not come on and need at least three inches of pedal travel to activate.
