Hydraulic Brake light switch questions....

I recently changed master cylinder when I did a 4 speed conversion. The car has a hydraulic in-line brake switch mounted in the left front brake tube between the master cylinder and the caliper. It does work, but seems like I have to push brake pedal down quite a ways before tailights come on.
1) is this switch adjustable?
2) are their different "ratings, or different settings" switches?
3) should I convert to some sort of electric switch?

I want the lights to come on as soon as I hit the pedal....
Thanks in advance.....:thumbup:

hydraulic in-line brake switches do not last .
I've seen this statement a few times, but always wondered how Ford successfully used them for decades with very few failures? Are the new switches junk, compared to what Ford used?
I just tossed an old Ford pressure switch away that was on my '63 Falcon, and it appeared original; still working. I replaced it when I swapped the old single bowl master with a dual bowl Mustang master. I also installed a new hydraulic switch, so I hope it keeps working.
I don't see any hesitation or delay with brake pedal pressure and brake lights coming on. I wonder if installing a pressure switch farther from the master could somehow be the source of needing more pedal pressure to bring the lights on?

well in all fairness most things built in the day were made to last. today it is throw away 1 or 2 years. had a perfectly good stove was in the house when i bought it and it was most likely 20 years old. well redid the kitchen so out it went. new one in place one burner out in the first 2 years. that old stove is still in use, i bake my small powder coated parts in it.

ok back to the hydraulic switch they leak internal , port can get clogged and restricting flow, if mounted wrong like vertically or upside down it can hold air.
