ABSTRACT:
An improved PTC thermal protector device is disclosed wherein the PTC element is protected from excessive mechanical forces such as shear forces that would otherwise significantly degrade PTC performance. The PTC element is protected by one or more adhesive masses in contact with both terminals of the device. The improved PTC thermal protector device does not require the use of specially designed terminals or terminal attachments, yet is simple to assemble on a mass-production basis.
