Description

These 12V DPDT relays are small but ideal for projects to allow various control options, including changing the direction of a motor. 

DPDT stands for double-pole double-throw relay which is an electromagnetic device used to separate two circuits electrically and connect them magnetically. They are often used to interface an electronic circuit, which works at a low voltage to an electrical circuit which works at a high voltage. 

A DPDT relay can also be used to change the polarity at the terminals of a device connected at output. In case no input signal is given, the motor would rotate in one direction and when an input signal is provided, the connector change their positions, resulting in the anticlockwise rotation of motor.
