Abstract
Abstract A radar warning receiver is provided including a plug adapted to be received within a vehicle cigarette lighter socket, wherein the plug incorporates a metal plate having (1) a foward end to which is provided a pair of outwardly bowed resilient spring arms which extend exteriorly of the plug to make electrical, physical and thermally conductive contact with the vehicle cigarette lighter socket and, (2) mounted thereto a power regulating device. The thermally conductive contact permits reduction in the size of the gripping end of the plug. Accordingly, the gripping end of the plug is sized to be conveniently gripped between the thumb and fingers of a human hand.
