Solid state relay module

A solid state relay module, comprising:

• a first solid state switch configured to establish and break an electrical connection between a first high-voltage input terminal and a first high-voltage output terminal disposed on a power circuit board;
• an electronic controller in communication with the first solid state switch and configured to put the first solid state switch in a conductive state or in a nonconductive state;
• a top cover formed of an electrically insulative thermoplastic material, wherein the power circuit board is disposed within a cavity defined by the top cover and wherein the top cover defines a plurality of openings through which the first high-voltage input terminal and the first high-voltage output terminal extend;
• a bottom cover formed of a thermally conductive material in thermal communication with the first solid state switch;
• a compliant thermal interface paste disposed between an inner surface of the bottom cover and surfaces of the first solid state switch;
• and
• a resilient thermal interface pad attached to an outer surface of the bottom cover by a first adhesive layer on an inner surface of the resilient thermal interface pad.
