ABSTRACT:
A fruit/vegetable blender having a multi-speed control switch comprises a speed controller mounted on the motor house thereof, for controlling power on/off and motor speed. The speed controller utilizes a variable resistor, a flexible conducting-plate, a conducting slider, a push button, a slider handle and a plurality of conducting ports along the variable resistor to provide a resistance adjusting mechanism, thereby the motor speed changing accordingly. The multi-speed control switch is further protected by an inner retaining plate, an outer retaining plate, a wavy plate and a water-resistant pad from water infiltration.
