Question
Please draw or multisim this circuit! Devise a scheme using a relay with double-pole double-throw contacts to apply opposite-polarity voltages to the rotor of a small DC motor upon the throwing of a single-pole single-throw "DIRECTION" switch. Your design should also include a separate "ON/OFF" switch in order to stop the motor before changing directions. The relay will be energized when 12 Volts is applied to the coil. The motor supplied will require a voltage other than 12 Volts to operate, so be sure that your design allows for a separate motor supply. As part of your design, provide an indication of the direction of rotation by illuminating -- a Red LED when the motor is turning CLOCKWISE a Green LED when the motor is turning COUNTER CLOCKWISE.Explanation / Answer
The DPDT relay (Double Pole Double Throw) is quite interesting and can be used in various scenarious, including for changing the direction of a motor as you can see in the picture below. It has 2 terminals and 4 connectors and you can look at the DPDT relay as the equivalent of 2 Single Pole Double Throw SPDT relays.
