PTC device

A PTC device comprising a PTC material sandwiched between a pair of metal terminal plates having outer surfaces that define opposite faces for said PTC device, said device having an outer periphery that includes opposite ends and opposite sides, each said plate having an integral leg extending outwardly therefrom along one of said sides adjacent each of said ends to provide a total of four legs that include a pair of legs adjacent each of said ends, each leg in each of said pair of legs having a first portion extending transversely outwardly from the metal terminal plate with which it is integral and having a second terminal portion extending generally parallel to the metal terminal plate with which it is integral, and at least one leg in each of said pair of legs terminating in a hook portion that extends generally parallel to said opposite faces toward another hook portion in another of said pair of legs.

A PTC device comprising a PTC material sandwiched between a pair of opposite terminal metal plates, a plurality of spaced-apart legs extending outwardly from at least one of said plates integrally therewith for reception in slots in a circuit board, at least one of said legs terminating in a hook portion that extends transversely of said one of said legs in outwardly-spaced relationship to the metal terminal plate with which it is integral for retaining said one of said legs in a circuit board slot.

A PTC device comprising a PTC material sandwiched between a pair of substantially parallel flat metal plates, said plates having substantially parallel flat outer faces and said device having a predetermined thickness measured across said faces, a pair of legs projecting from said plates integrally therewith and having substantially flat terminal portions that project outwardly from said plates substantially parallel to said faces and are spaced-apart apart in the direction of said predetermined thickness a distance that is substantially greater than said predetermined thickness.

A PTC device comprising a PTC material sandwiched between a pair of substantially parallel flat metal plates, at least one of said plates having at least one integral hooked leg extending therefrom, said leg having a flat portion that projects outwardly substantially parallel to said one of said plates and terminates in a hook portion that is spaced outwardly from said one of said plates and extends transversely of said flat portion in a direction substantially parallel to said one of said plates.

A PTC device comprising a PTC material sandwiched between a pair of substantially parallel flat metal plates, said device having opposite ends and top and bottom sides, at least one hooked leg on at least one of said plates extending outwardly from said bottom side, and at least one standoff projection on at least one of said plates extending outwardly from said bottom side, said leg having a leg length and said standoff projection having a standoff projection length, and said leg length being substantially greater than said standoff projection length.
