I had a broken one I took apart, see photos, I reassembled it, drilled out the old wire, soldered in a new one, patched it up with some JB weld, shrink wrapped the ends, or you cold try the liquid electrical tape
with the bake light so shabby, the little tabs/plungers thingys did show a little wear. so on one I attached some small springs so it would return to its original postion. they test fine, but my car is not yet ready for to give them the real test.
