The Wrestling Switch is a classic reversal used by all folkstyle wrestlers, but I believe it is definitely under utilized by BJJers. This video goes over a transition from the Switch to the Knee Compression, which can then be transitioned into the Truck as well.
Some details to pay attention to hear are the control of the foot – focusing on grabbing around the toes instead of the base of the ankle. Another tip here is using the free leg to push your foot deeper into the bend of the knee. Finally, make sure you point your toes towards the bend of his knee for maximum penetration.
