Our current pick-ups (50707) provide optimal electrical contact in all commercially available coaches and are easy to install: simply glue them to the underside of the bogie so that the pre-tensioned contact strips touch the inside of the wheels (wheel flange). Since each set consists of two sprung contact strips one set per axle is enough. Suitable for any axle spacing. Suitable for H0 DC and AC or N gauge. Set with 8 current pick-up contacts sufficient for 8 axles.
