Claim:
An electronic control enclosure comprising: a enclosure housing defining an interior chamber, the enclosure housing including a first wall, an opposing second wall, and a third and opposing fourth walls extending between the opposing first and second walls; a heat sink located at least partly in the interior chamber, the heat sink including a contact arm extending generally parallel to the second wall and a locator protruding from the contact arm; a spring aligned with and projecting toward the contact arm; a substrate assembly including a generally planar substrate having opposing first and second surfaces and a recess disposed into the first surface, the substrate assembly further including an electrical component, the electrical component having a heat transfer surface; wherein when the substrate is inserted into the enclosure housing such that the locator contacts the first surface, the substrate compresses the spring and is spaced apart from the contact arm; and when the substrate is inserted into the enclosure such that the locator is received in the recess, the spring urges the heat transfer surface against the contact arm.
