Abstract
An adjustable electrical device, such as a trimmer capacitor, comprising a housing and an electrode movable relative to the housing, the electrode comprising a screw-threaded portion which is resiliently deformable to allow compliant threaded engagement with a complementarily screw-threaded portion of the housing of slightly smaller diameter. The screw-threaded portion is split to allow said deformation, the split being in the form of a slot extending across the screw-threaded portion, parallel to the rotational axis of the screw-threaded portion. A further slot is located at the base of the screw-threaded portion, which interconnects with the slot. The electrode is provided with an actuating member having a head portion adapted to receive an adjusting tool, such as a screwdriver, and a body portion which is an interference fit within the electrode.
