brake lights not working
 
I have a 1964 chev. If I take the switch out of the loop, the brakes lights work (i.e. I disconnect the switch's output wire and apply 12v to the wire the brake lights immediately come on).

If I isolate the switch, it too works (i.e. I disconnect both switch wires and apply 12v to the input terminal of the switch and I step on the brake and I see 12v on the output terminal of the switch).

If I then reattach the switch wires and step on the brake, I see 12v going into the switch and nothing on the output side.

I'm guessing here - the switch will work under a no load situation but cannot handle the required load of the brake lights and needs to be replaced?

Remove the switch from the bracket, leave the wires attached, and see if it works....... if it does then you have to adjust the travel of the brake rod/sheft etc..... to the switch it's self

You are correct. The switch is bad. Loose internal connection, corrosion or dirt. Just replace it.
