Abstract
This invention relates to fuses for electrical plugs and more particularly to a high and low overcurrent stratified fuse for use in a low power electrical circuit. The fuse has a layered construction in which a particulate conductive link is cooperatively applied and adhered to a heat deformable substrate. The substrate in a further preferred embodiment is thermally isolated by an insulating layer abutting the substrate on the side opposite the conductive link. The conductive link melts or disintegrates in response to high over current conditions. The substrate deforms and breaks the conductive link applied thereto in response to low over current conditions.
