An adjustable electrical device, such as a trimmer capacitor, comprising a housing (14) and an electrode (30) movable relative to the housing, the electrode (30) comprising a screw- threaded portion (32) which is resiliently deformable to allow compliant threaded engagement with a complementarily screw-threaded portion of the housing (14) of slightly smaller diameter. The screw-threaded portion (32) is split to allow said deformation, the split being in the form of a slot (36) extending across the screw-threaded portion, parallel to the rotational axis of the screw-threaded portion. A further slot (34) is located at the base of the screw-threaded portion, which interconnects with the slot (36). The electrode (30) is provided with an actuating member (38) having a head portion (42) adapted to receive an adjusting tool, such as a screwdriver, and a body portion (46) which is an interference fit within the electrode.
