Yes it is a good service that is needed and I hope you find the right commercial switch that works. I gave up after trying 3 different ones. Maybe the type used was the issue as I tried NC snap action. Ones I could find were not precise enough--an eight of turn in adjustment made it come in just right or too late so didn't trust them. Maybe there is one out there.

Have you given thought to drilling out the (assumed) broken or burned contact they use and replacing those with a long rivet or maybe a brass screw so the ball could still be used? Problem I saw there was not trusting any adhesive to ensure something didn't move & short--although maybe some threads. The last one I fixed used a piece of phenolic on top of the contacts that pressed against the inside of switch hsng. Nice little oval recess already in bakelite worked well for keeping it in place. Made a hole for the plunger to pass & push ball. I reattached by drilling & tapping thru metal into bakelite and installing a few setscrews then the rubber to cover.
