Four switches are connected in between ve supply and ground and dc motor is connected in between two switches as shown. The most common use of an h bridge is to drive a dc motor allowing directional control. When you can control two motors to go either forward or backward you can build yourself a robot. In the most simplistic terms an h bridge circuit can switch the polarity of the attached load.
