A machine ( 10 ) for mixing food in a cup (C) includes a housing having an agitator assembly ( 15 ) extending downwardly therefrom and adapted to be rotated by a motor to mix food in the cup (C). A switch assembly ( 20 ) is provided to operate the agitator assembly ( 15 ). The switch assembly ( 20 ) includes a bracket ( 21 ) which pivotally carries a plate ( 41 ) which extends downwardly adjacent to the agitator assembly ( 15 ). A switch ( 31 ) is carried by the bracket ( 21 ) and has an arm ( 36 ) biased toward the plate ( 41 ). The plate ( 41 ) is biased toward the arm ( 36 ) by springs ( 50 ) to maintain the switch ( 31 ) in the open position. Pivoting the plate ( 41 ) relative to the bracket ( 21 ) against the bias of the springs ( 50 ) allows the arm ( 36 ) of the switch ( 31 ) to pivot to close the switch ( 31 ) allowing the agitator assembly ( 15 ) to rotate. Releasing the plate ( 41 ) allows the springs ( 50 ) to bias the plate ( 41 ) against the arm ( 36 ) but a pad ( 55 ) silences any noise created thereby, and a wall ( 28 ) of the bracket ( 21 ) stops the plate ( 41 ) from exerting undue pressure on the arm ( 36 ).
