Brake lights not turning on ! Could be an easy fix ?

I’ve been needing to test this especially right before I need to install the one I already ordered or maybe just need to follow up what might be failing the TS switch. Thank you a lot I didn’t know there were so many other functions that the TS switch had towards positions and such
BTW you can jumper between the 2 wires attached to the brake light switch and the brake lights should light.

The brake light switch brakes the connection when the brake pedal is in the up position, the switch is depressed.

When you press the brake pedal the plunger on the switch comes out and makes the connection between the two wires passing power to the brake light bulbs
