The invention relates to a tabletop device for mixing and discharging multi-component compounds, particularly a dental impression compound, having discharging plungers (8a, 8b), a motorized drive (24) for the discharging plunger (8a, 8b), a switchable coupling (30) for the coupling or decoupling of the discharging plunger (8a, 8b) to or from the motorized drive (24), and at least one handle (3a, 3b) for the displacement of the discharging plunger (8a, 8b) to be carried out manually in the decoupled state thereof. In order to minimize the design effort of such a tabletop device, the invention provides that the switchable coupling (30) comprises a coil spring (34) for the releasable frictional connection of the drive side (31) to the output side (14) of the coupling (30).
