I have a picture of a device's handpiece and I want to know the applicatioan of its components but I'm confused about one of them.

Can anyone help me to figure out what this is component? (Marked with a red rectangle in the picture.)

enter image description here

  • \$\begingroup\$ there is printing on the component ... why is that information not included in your post? \$\endgroup\$

It's a thermal fuse for safety. It cuts power to something when that thermal fuse heats above the limit.
