Abstract
A surface mount overheat indicator device includes a flattened annular outer frame and an inner fusible disk positioned within the outer frame. The fusible disk is formed of a material which melts at a selected temperature. The outer frame has a plurality of adhesive relief apertures formed therethrough in circumferentially spaced relation. The fusible disk projects rearwardly of a rear surface of the outer frame to define an adhesive receiving space between the rear surface of the outer frame and a surface on which the device is adhesively installed. The adhesive receiving space and the adhesive relief apertures cooperate to prevent the positioning of a layer of adhesive or a pocket of air between the fusible disk and the surface on which the device is installed to avoid interfering with the transfer of heat therefrom.
