My 1936 Chevrolet uses an hydraulic switch. I don't know why they would then go mechanical. Does anybody know why?

Because hydraulic brake light switches are an unholy abomination.

 

They are prone to leaking, prone to failing, loaded right to their electrical limit when asked to operate TWO brake lights on a 6 volt car (pretty much eliminating the possibility of brighter bulbs), are usually incompatible with silicone brake fluid, and in their original form require more pressure to operate, delaying brake light warning to the cars behind.

 

Some of the latest ones do have a lower "on" pressure than the old originals, but the brake lights are still more delayed than a properly set up mechanical switch that typically triggers whenever your foot is on the pedal, whether you are slowing or not.

 

Four or five years ago I had one short to ground and try to burn up the wiring harness. I cant imagine why these hydraulic things were still used into the 1960s on some makes, but they were.
