ABSTRACT:
A disc assembly for a bimetallic disc-actuated thermostatic switch is adapted to minimize response time. The switch includes a disc assembly comprising a disc retainer, and a bimetallic disc and a cap on the disc retainer. The disc retainer includes a central hub portion, a plurality of fingers which radiate outwardly from the hub portion, a plurality of disc retainer projections on the fingers adjacent the terminal ends thereof and a plurality of disc support shoulders on the fingers adjacent the disc retainer projections thereon. The fingers have open notches therebetween for reducing the cross sectional area of the material available in the disc retainer for conducting heat from the bimetallic disc to the body portion of a thermostatic switch on which the disc assembly is installed. The cap includes an end wall portion having an enlarged opening therein and a skirt portion having a plurality of apertures therein which reduce the cross sectional area of the material available in the skirt portion for conducting heat from the bimetallic disc to the body portion of a switch.
