I had to get air out of the line leading to the switch to get it to activate. The line came down from the dash to the top of the switch, which is mounted vertically in my case, but inside the car, mounted lower than the master cylinder. The tee is before the line lock and proportioning valves, as you have done.

As there was no bleeder, the flare nut that connects the line to the switch's fitting was loosened to allow fluid to spill out when the pedal was pressed. Tightened it while the pedal was down, then repeated.
