Bed not heating - heater_bed not heating

Hello everyone, my bed was working smoothly. Late night I was burning ASA so my bed was working between 110-105C. I put it to heat and then this message appeared. I checked other posts and probably it's the thermal fuse. So I have two questions: 1) What are the specs of the thermal fuse, just in case I have to change it? 2) Can I, instead of using a thermal fuse, use a thermal switch? Because if it keeps going off (I plan to work with Nylon a lot) I don't want to keep changing fuses. I'll perform some checks in a few hours to confirm it's the thermal fuse, but I'm almost sure it is. Thanks in advance!
