A mixer includes a primary operating switch for connecting the mixer to a source of electrical energy and a secondary operating switch for selectively increasing the power of the mixer. The primary operating switch is movable between a first position whereat the mixer is disconnected from the source of electrical energy and a second position whereat the mixer is connected to the source of electrical energy. The primary operating switch includes a stop. The secondary switch is movable between a first position whereat the mixer is operating at normal power and a second position whereat the mixer is operating at increased power. The stop of the primary switch is disposed in the path of travel of the secondary switch when the primary switch is in its first operating position to prevent the secondary switch from being placed into the second position thereof. The stop is displaced from the path of travel of the secondary switch when the primary switch is placed into its second operating position.
A mixer having a primary operating switch for connecting the mixer to a source of electrical energy and a secondary operating switch for selectively increasing the power of the mixer, said primary operating switch being movable between a first position whereat the mixer is disconnected from the source of electrical energy and a second position whereat the mixer is connected to the source of electrical energy, the primary operating switch including stop means, said secondary switch being movable between a first position whereat the mixer is operating at normal power and a second position whereat the mixer is operating at increased power, said stop means of said primary switch being disposed in the path of travel of said secondary switch when the primary switch is in said first position to prevent said secondary switch from being placed into said second position thereof, said stop means being displaced from said path of travel of said secondary switch when the primary switch is placed into its second position.
