What component is this?

Hello! I bumped into component shown in the pictures, but I don't have a clue what that is. Does any of you know what it is? Markings on the component says: "Z66/67" and "T180".

Re: What component is this?

does it press on something when it's mounted?
it's copper so it may be a thermal switch.
the fact that there is a thermal fuse inline as a backup may prove this.
"T180" - could be the temperature
the thermal fuse will blow at 230'

Oh yes, it is thermal switch! I wondered that I can't get any kind of readings from it, but I heated it beyond that 180 degrees centigrade and it started to conduct. Thank you stj from your tip! Never seen one of those before, and Googling didn't helped...

And yes, it presses against metal plate.
