I know my switch works, I measured it with a meter. And the wiring is OK; the brake lights work when I connect the two wires.. So what's the problem?
I guess the plunger doesn't reach the brake as I can't screw the switch all the way. How deep do I have the screw in this switch? I think I tried the lights (measured Ohms) at 1000 positions but none seems to work.
Then I got fed up with it and just installed an extra bracket for mounting the switch as a temporarely solution...
PS this is my first post, I will soon introduce myself and the car in another topic

I had similar probs with my S2 Esprit.
The depth that the switch screws into the pedal box is absolutely critical. If its not screwed in enough, or not far enough, then either the lights are on permanently. or not at all.
With the ignition on, disconnect the two wires from the switch (so you don't tangle them up.
Then screw the switch into the pedal box and reconnect the wires, go to the rear of the car and see if the lights are on. If not then disconnect the wires, screw the switch in a little further and try again. Keep repeating until the lights come on. At that point back the switch off a little, and then reconnect and check for correct operation.
Its a lot quicker if you either
a) Have a second person at the back of the car to relay what is going on
b) Park the rear facing a glass window so you can see the reflection of the lights from the drivers seat.
You should have a lock nut on the switch so that when you get the correct depth you can lock it off. Incidentally I also had an issue that the switch worked with a tester but wouldn't work in the car. No idea why, but a new switch was about £3.00, so I just bought a new one. They are a very common 1970s British Car Part.

Best of luck.
It really is very simple......just incredibly complicated to explain.
