We present the design, manufacturing and performance of the horn-switch systemdeveloped for the technological demonstrator of QUBIC (the Q&U Bolometric Interferometerfor Cosmology). This system is constituted of 64 back-to-back dual-band (150 GHz and 220 GHz) corrugated feed-horns interspersed with mechanical switches used to select desiredbaselines during the instrument self-calibration. We manufactured the horns in aluminumplatelets milled by photo-chemical etching and mechanically tightened with screws. Theswitches are based on steel blades that open and close the wave-guide between the back-to-back horns and are operated by miniaturized electromagnets. We also show the currentdevelopment status of the feedhorn-switch system for the QUBIC full instrument, based onan array of 400 horn-switch assemblies
