<p>A pump (10) for a beverage preparation machine comprises: a heat-radiating electric arrangement (35); and a thermo-fuse (20) connected to the electric arrangement via an electric connection (21', 60''). The thermo-fuse is connectable to a power source for powering the heat-radiating electric arrangement via the thermo-fuse. The thermo-fuse is in thermal communication with the heat-radiating electric arrangement so as to disconnect the electric arrangement from the power source when the thermo-fuse reaches a predetermined maximum temperature in reaction to an excessive heat radiation from the electric arrangement. The thermo-fuse and the heat-radiating electric arrangement are so configured that heat radiating from the electric arrangement (35) to the thermo-fuse (20) is predominantly conducted along the electric connection (21', 60'') from the electric arrangement to the thermo-fuse.</p> |
