A multi-value capacitor with a safety disconnect mechanism has a capacitive element with six capacitive sections, a common wire, and six section wires enclosed in a cylindrical metal can with a metal lid that normally has a concave configuration. The wires are soldered to contacts extending through the concave metal lid. The safety disconnect mechanism includes an external insulator disk with terminals. The terminals in the insulator disk align with the contacts in the metal lid. The center common terminal of the insulator disk is fixedly riveted to the center common contact of the metal lid. Spring elements form the electrical connection between the section terminals of the insulator disk and the section contacts in the metal lid. If an overload condition occurs, pressure inside the sealed metal can causes the metal lid to spring from its concave configuration to a convex configuration, which causes the whole insulator disk to pop up and thereby simultaneously break the connection between all of the section contacts in the metal lid and the section terminals of the insulator disk. |
