A combination “Spring Clamp” and “Push Wire” "Lighting Connector" (WAGO Series 224) – showing a typical unit, disassembled units and views of the combination mechanism – using a “Push Wire” connection (for solid wires) and a “Spring Clamp” connection for either solid or stranded wires. Note that a "Clamping Spring" clamps each stripped conductor against a common "Connection Plate" - which provides increased connectivity between the conductors.
