Stun Guns work by basically generating “electrical noise” that the sensory nervous system interprets as pain or discomfort. This “noise” interrupts the electrical signals that communicate messages back and forth from the brain to the rest of the body. Like communication traveling over the internet or telephone system, these communication messages run through nerve cells that branch throughout your body. They carry information from the brain about how the muscles should move or from your finger tips back to the brain telling how something feels.
The basic idea of the stun gun is to confuse this communication system by delivering a high voltage (very fast) combined with a low amperage (low intensity) charge to temporarily confuse the attacker’s nervous system which eventually leads to disable an attacker for several minutes (depending on the attacker’s body strength, mentality and pain tolerance). The high voltage allows the charge to quickly pass through clothing and skin, but the low 3-milliamp amperage is not intense enough to damage the attacker’s body (unless applied for an extended period of time). Therefore, unlike lightening with high amperage, the electricity from a stun gun is non lethal.
