Must appliance switch replacement be perfect match?

I need to replace the switch on a DeLonghi Solaris oil-filled radiator-style space heater. DeLonghi doesn’t offer this part. The manufacturer of this part is Chinese and doesn’t seem to sell products in the U.S. except maybe to manufacturers. I can’t find a DUAL rocker switch of a similar size with these specs: 16a 125VAC, 10a 250VAC. I don’t even know if “16a…etc” is the most important thing to look for.

MY QUESTION: I’ve found switches whose specs were close to "16a 125VAC, 10a 250VAC,” but I don’t know if I must have a perfect match or if my specs might represent minimums and the specs of other switches might indicate a broader application in which my heater would fit. It’s getting chilly in my office and I’m wondering if I have to trash this heater or if there might be a switch out there that I can use. Thanks!
