Questions about this item

Should I pick the 130C or 266F version?

They are the same switch — 130 Celsius equals 266 Fahrenheit — so either label points to the identical 4-pack.

What does the 130C rating actually do inside my appliance?

The contact stays closed until the mounting surface hits 130 Celsius, then opens to cut power; it closes again automatically once the surface drops roughly 5 degrees.

How much current can the AC 250V 10A terminals handle in practice?

The switch is rated for 10 amps at 250 volts AC, with a circuit resistance of 50 megohms and insulation resistance of 100 megohms, and it withstands 1500 volts AC for one minute.
