A light dimmer capable of receiving a faceplate fastener while thermally insulating the fastener from a heat-generating device, such as a triac or a field-effect transistor, is presented. In a preferred embodiment, the dimmer includes a thermally insulating boss integrally formed with the body of the dimmer such that the boss includes a fastener-receiving aperture adapted to be axially aligned with the fastener-receiving openings of the faceplate. In addition, the dimmer includes a heat-dissipating aluminum yoke to which the heat-generating device is in thermal communication, thereby allowing the yoke to act as a heat sink. The yoke has a fastener-receiving aperture formed therein in axial alignment with the fastener-receiving aperture of the thermally insulating boss, with the yoke fastener-receiving aperture proportioned to receive the fastener therethrough in non-contacting relationship.
