Stun guns are non-lethal weapons that incapacitate potential attackers. They work by delivering an electric shock to the attacker's body, which causes temporary muscle spasms and confusion, thus allowing the user to escape safely. Stun guns can be operated in a variety of ways. Some require the user to press a button on the device, while others require simply making contact with the attacker’s body. Most modern stun guns use batteries and deliver an electrical current through two electrodes when activated. When used properly, stun guns can provide safety and security against physical threats. However, they should be used with caution and respect for both sides involved in a potentially dangerous altercation.
