ABSTRACT:
A gear motor having an output shaft for driving the dispensing mechanism of a vending machine includes a plurality of magnetically operated switches positioned adjacent one end of the output shaft and a plurality of magnets attached to that end of the output shaft. A DC electric motor is energized by a computer to rotate the output shaft in a first direction until one of the magnetic switches is actuated by a magnet, which instructs the computer to reverse the polarity of power to the DC motor, reversing the direction of the motor and the output shaft. When the output shaft is returned to its standby position, one or more of the switches are again actuated which instructs the computer to terminate power to the DC motor. An enclosure surrounds the switches and magnets and protects them from the ambient.
