Abstract
A composite circuit protection device includes a laminar insulating member and first and second laminar circuit protection devices. Each of the first and second laminar circuit protection devices includes (1) a first laminar electrode, (2) a second laminar electrode, (3) a laminar PTC resistive element which (i) exhibits PTC behavior, (ii) has a first face to which the first electrode is secured and an opposite second face to which the second electrode is secured, and (iii) defines first and second apertures which run between the first and second faces, (4) a third laminar conductive member which (i) is secured to the second face of the PTC resistive element in the area of the first aperture, and (ii) is spaced apart from the second electrode, (5) a fourth laminar conductive member which (i) is secured to the first face of the PTC resistive element in the area of the second aperture, and (ii) is spaced apart from the first electrode, (6) a first transverse conductive member which lies within the first aperture defined by the PTC resistive element, runs between the first and second faces of the PTC element, is secured to the PTC element, and is physically and electrically connected …
