There are many kinds of electric shock sticks, and different currents will have different effects on people. If the current of 4 mA is applied to the neck, it may cause electric shock. 10 mA to 30 mA will cause muscle spasm, which will be dangerous for a long time. More than 30 milliamps is life-threatening. A current of more than 250 mA can kill a person's heart in an instant.

The basic condition of this electric shock instrument is that it needs small current and high voltage. Generally, rechargeable batteries are used as power supply, and tens of thousands to hundreds of thousands of volts are obtained through impulse boosting and high-voltage and double-voltage rectifier circuits. With this kind of high-voltage discharge, people are dizzy, because the current is very small, which generally does not pose an obstacle to life. The time of fainting is related to the voltage and the tolerance of the shocked person.

Precautions:

When using the self-defense defibrillator, the handle of the self-defense defibrillator is usually held by the right hand, and the safety cover is put on the wrist to prevent gangsters from grasping or throwing it too hard. Press the shock button at the handle with your thumb.

At this point, there is a jumping blue arc between the top contact and the metal discharge bar. When the contact and the metal discharge rod come into contact with human skin, the victim will have a kind of severe numbness and pain, which makes him feel nervous and afraid, forcing him to yield.

Once the electric shock opponent touches the other person's skin, he should immediately withdraw the self-defense defibrillator, and do not touch the skin for a long time, otherwise the power of the self-defense defibrillator will be affected. The lighting hand holds the self-defense defibrillator and presses the red lighting switch near the discharge rod in front. At this point, the lighting should be on. The alarm hand holds the self-defense defibrillator and presses the S button of the middle alarm switch, which will give out a continuous alarm sound from weak to strong.
