defrost limit switch specification ?

Does anyone know the limit temperature of the defrost/thermo switch ? Also the range ?

The heater works fine and has been modified with numerous copper wires going around the cal-rod and up into the evap core. I need to replace the switch and don’t want to have to pull out the evap to undo all the copper wires.

Unfortunately I already threw away the old limit switch and did not look at the numbers on it before I did … Yes I know. Dumb move on my part.

The heater and defrost termination switch come together.

No idea of its range.
