How a Stun Gun Works

When you purchase a stun gun it is important to understand the mechanics and the principles behind the operation of a stun gun. This will help you manage the personal protection device and use it most effectively for self defense.

Stun guns work to disrupt the body's electrical pulses that are sent from the brain to the limbs and other parts of the body. When a body is functioning properly, electrical signals or neurotransmitters are sent from the brain to make every function occur which includes smiling, touching, moving your arms, legs, control over your bladder, talking, and everything else your body needs to do. Stun guns send 1-3 milliamps, which disrupt the body's electrical system causing it to temporarily shut down.

What happens when stun guns are used is that the body is temporarily paralyzed because the signals from the brain to the various muscles are being disrupted. The brain is confused and shuts down for a moment. When a stun gun works it tells the body to shut down for a short period of time. Because of all this confusion the muscles start to work extremely hard trying to figure out what they are supposed to be doing. This takes a great deal of the energy from the body by depleting the blood sugar in the body and incapacitating the attacker for a short period of time.

Stun guns use 9 volt batteries or are rechargeable. They have internal transformers designed to increase voltage and reduce the amperage that is passed into the body. An oscillator is integrated into the circuitry which works to produce the pulsing action. The charge is built up with a capacitor and the electrodes are responsible for delivering the charge. These are the only elements of a stun gun. Stun guns send voltages ranging from 200,000 to 1,000,000 or more. This is more than enough to go through the thickest of jackets and clothing. Only 3 milliamps of current are used which is why there is never any long term damage to the body.

The great thing about stun guns is that when the current is unable to flow across the double electrodes in the top, the current will go to the two test electrodes. They are close together which allow the flow of energy to leap between each of them. As the current moves it ionizes the air particles and results in a spark that is visible. You can also hear a loud crackling noise that is very intimidating. The purpose of this is so that an attacker can see that you have a stun gun. Usually the visible sign of the electrodes sparking and the sound of the crackling is enough of a deterrent for personal protection. Most attackers will go away.

Stun guns are very basic. There are many different types of stun guns and they come in many shapes and sizes. However, they all use a 9 volt battery or are rechargeable and have the same capabilities to send 3 milliamps into the body and disable the electrical signals or neurotransmitters being sent from the brain. The body will be temporarily disabled for a short period of time.

Keep in mind that when stun guns are used, the electrodes have to be touching the assailant. They are very effective in disabling a person and temporarily paralyzing them. You cannot kill someone when you use a stun gun on them. Also, the voltage going into the attackers body will not pass back to you even if you are touching the attacker.
