Brake lights and hazards not working! Help

Key doesn't have to be on. Was there 12 volts on the pink wire going to the switch? Try replacing the switch. Dirt cheap on rock auto. I saw one that was $3.00.
Ok I replaced the switch. Here is what I have discovered. If I touch a probe to the pink lead wire in to the switch I get 12 volts. When I touch the probe to the terminal with the white wire attached I get .04 volts. Here is the strange thing, if I disconnect the white wire from the tab and probe the tab (terminal) I get 12 volts! As soon as I attach that white wire the voltage drops to .04 volts.. I don’t understand the system so not sure if this is correct or not. My brain doesn’t compute how the voltage goes away when I connect the white wire
