Similar to what others are saying. Keep your arm and hand loose until the very last moment before impact, and then try to max out the power. That means your muscles will become tense very, very briefly around the time of impact, and then will relax again. It's in the transition from loose to tense that the snap comes.
I guess it will look like a punch without snap, but much quicker, because when your arms are relaxed they move much quicker.
BTW, the point of 'snap' is also the point where you can turn your shoulder in, turn your hip in and push off the ball of your back foot (for a straight). So you have to practice being able to get those all to happen at the same time.
