35 brake switch help

[Solo_909]

Hey fellas,

So my brake lights stopped working. I’m thinking it a the switch so I thought I’d make sure I get all the right stuff. When searching for brake light switches for a 35 ford coupe two different kinds show up.

This one



And this one

My brake cylinder uses the second one so has my 35 master been swapped with something else? If so with what?

Do I need to replace anything else besides the switch? What inside makes the switch work?

Thanks!
