A flashlight includes a source of power, a source of light, and switching circuitry connected with the source of power and the source of light. The source of light may be a semiconductor diode capable of emitting white light when energized. Touch-sensitive switch apparatus includes first and second terminals which are engagable by an operator of the flashlight to increase intensity of light emitted by the semiconductor diode. Third and fourth terminals are engagable by the operator to decrease intensity of the light emitted by the semiconductor diode.
