ROBERT D. WHELAN WIPER CONTACT FOR TURRET-TYPE VARACTOR CONTROLLER ABSTRACT OF THE DISCLOSURE The base portion of the wiper contact is deformable to assure continuous electrical connection between a lead screw and the aligned resistive strip located on the surface of the turret, as the contact is inserted therebetween, The strip engaging portion is located on the resilient base portion approxi- mately midway between the guide portion and thread engaging portion such that the deformation causes the contact to exert substantially balanced forces on the lead screw. The structure of the guide portion of the contact is designed to enhance mechanical stability by preventing dislodgement of the contact without the necessity for cooperation with other external parts which obstruct visibility of the position indicating member, which is mounted on the contact and extends over the entire width thereof. In addition, means are provided to prevent the relative lateral movement between the contact and the lead screw during lead screw "runoff".
