ABSTRACT:
An improved magnetically driven resistor gauge (50) which includes a plastic base and plastic cap hermetically sealed together by ultra sonic welding to isolate the interior (90) of the gauge from the external environment. A dedicated ground terminal (100) is molded into the cap to ensure an effective ground. A contact plate (118), forming a part of the pivotal pointer assembly, includes resilient arms (120, 121 and 122) which are in electrical contact with the ground terminal and resistance wire (94), respectively.
