HVAC inside fan wont turn off


Hello all, We just bought our house about a month ago and our HVAC system was working fine, then 2 days ago we noticed that the inside fan wouldn't shut off. We had our thermostat set to AUTO but even when we switched to off it stayed on.

I am not an electrician but I am pretty decent at fixing things and after several hours researching, I think it might be my limit switch. I took it out and started calling HVAC supply stores, but they all said they only sell to business. I've tried looking on line for the same part but being that the system is 20+ years old I am having an issue figuring out of all of the limit switches are compatible with my system.

I've attached two pictures of the switch I removed to see if anyone could help me find a compatible switch or a supplier that will sell to the public, preferably in the SoCal area.

TIA
