what part is this?

Hi all,

I need id and part number if any one can help.

75 midget 

the switch that threads into the brake splitter/ proportioning valve under
the steering column

in the engine compartment. Has a two wire plug. Is this the brake light
switch or brake warning

switch? Mine squirts fluid every time the pedal is depressed. I called auto
parts store and they said $56.00 and has to be ordered. For 56 bucks I want
to make sure I order the right part.

Thanks, Skip
