Troy Bolton tiller electric switch issues

I have three Troybilt Horse tillers, and have issues w/ two, that have faulty ignition switches. I want to replace the keyswitch GW-9230, but find it’s either not available or costs $60-$85, which is rediculous. Does anyone have a lead to reasonably priced replacements, other switches that would work or a workaround ? Thanks in advance for your assistance.:newhere:

I could not see why any old mower ignition switch would not work.
All that is needed is a switch to ground the magneto to turn it off unless they are electric start.
