Looking for a GM part number - Switch on powermaster unit

I am trying to locate the part number for the brake switch on the powermaster unit. It is a large switch with a 3-pin terminal, and looks similar to a GM oil pressure sending unit but larger.

I replaced this one about 4 years ago, and its failed again. I can't find my record of the last purchase, but I know I got from the GM dealer. Any help would be appreciated, thanks!

Found the old part number, it is 18018141 and has been superceded to 18038508 which is still available from General Motors. MSRP is $206.74 :(
