Abstract
A liquid level sender assembly constructed to minimize contact distortion and dither. A housing supports a resistive track and a pivot arm is connected to the housing. The pivot arm has a force transmitting member attached which interacts with a boss on a contact carrier which is also pivotably attached to the case. A space is provided in the fit of boss within the force transmitting member which allows the boss to remain in one position when the pivot arm vibrates in small oscillations, but causes the boss to move in response to larger movements of the pivot arm. Contacts on the contact assembly electrically cooperate with the resistive track to provide a variable resistor. The contact carrier receives only force components directed circumferentially about the axis.
