Abstract
A domestic electrical appliance has a base supporting a work bowl. A removable cover for closing the bowl is fixed to the base by a rotary coupling. A motor unit is housed in the base and rotates a working tool positioned within the bowl. A push button is provided for controlling operation of the motor unit. Depression of the push button to actuate the motor unit also prevents removal of the cover from the bowl. A safety lock is provided which moves automatically to its locked position upon depression of the push button and in its locked position prevents the push button returning to its initial retracted position.
