Dongguan Eidoll Elect. Co., Ltd sales the SWC SW-2XXT Series thermistat cutoff. The specification as bellow:

SW-2 Series uses a metallic fusible alloy melted when ambient temperature rises to melting point of the alloy. An electrical circuit of the thermal cutoff is opened with forming two separate balls at the edges of the leads by surface tension of the fusible alloy.

S.W.C Thermal cutoff contains a sliding contact, spring, and electrically nonconductive thermal pellet. Under normal operating temperature, the soled thermal pellet holds spring loaded contacts closed. So, Current flows from left lead to the sliding contact through the metal case. When the temperature reached to the designated functioning point, the thermal pellet melts, allowing the compression spring to relax. That is, spring expend, moving the sliding contact away from the left lead. The circuit is opened, breaking contact between the left lead and sliding contact.
