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?
