A small, low-power switch, such as a toggle switch, includes a plastic housing which surrounds a switching contact assembly and provides a mounting for an electrically conductive handle. To ensure adequate grounding of the handle, the housing is made of two parts. A first portion made of insulating plastic surrounds the switching contact assembly and insulates it from the handle, as well as other components. A second portion made of conductive plastic is integrally molded to the first portion and is in electrical contact with the handle. The second portion also includes suitable structure for adapting the switch to be mounted on, or otherwise connected to, a grounded conductor, to thereby ground the handle.
