<p>A power take-off adapter for a conductor track, the conductor track (20) comprising a coupling slot (28) and a plurality of phase conductors (L1, L2, L3) extending longitudinally in the coupling slot, the power take-off adapter being arranged to be connected electrically and mechanically to the conductor track (20) and comprising a frame part (2), a phase-contact finger (4) arranged to protrude from the frame part (2) to form an electrically conductive connection to a phase conductor (L2) of the conductor track (20), a coupling contact (6) arranged to lead current to an electric appliance supplied by the power take-off adapter, and a connection contact member arranged to lead current from the phase-contact finger (4) to the coupling contact (6). The connection contact member comprises a helical spring (8), the connection contact member being arranged in such a manner that, in use, the entire load current flowing from the phase-contact finger (4) to the coupling contact (6) flows via the helical spring (8). The frame part (2) comprises a proximal location (41) for the phase-contact finger and a distal location (42) for the phase-contact finger, both of which are arranged to receive the phase-contact finger (4), the phase-contact finger (4) being arranged to be moved between the proximal location (41) for the phase-contact finger and the distal location (42) for the phase-contact finger, the helical spring (8) being arranged such that it is able to apply an axial force to the phase-contact finger (4) both when the phase-contact finger is in its proximal location (41) and when it is in its distal location (42).
