A static switch is a switch that uses the electrostatic current that flows through the human body to power on or off the device.
can dc volts kill you? It is in relationship to the amount of time the body is conducting the milliamp current. With your DC static charge, once the potential voltage has equalized by grounding the current flow stops. On a 240 volt system the voltage remains constant thereby causing the current to continually flow through the body. If you have ever has an electrical shock you know the feeling.
Current flows from the voltage source to ground. If an appliance is not grounded somehow the hot were to touch the metal case and you touched the case while standing on the ground then the current would try to travel to ground through your body. I once was called to debug a situation in a residence in Florida where the owner got a shock everytime he took a shower. Turns out the main electric panel had never been grounded to earth and thus the whole house was floating above earth ground. Essentially all the metal pmumbing was at about 60 volts above ground. When taking a shower the water stream conducted the current through the owner's body to the metal drain which was earth grounded.
If the wire is carrying an electrical current, and if the current has enough voltage, the current can leave the wire and pass through your body. This is painful, and can causes burns or death.

Static electricity is the BUILT UP STORE of electron charges [e-] between a pair of objects, while current electricity is the FLOW of electrons between these objects. Static electricity is a transfer of charge from one static body to another, resulting in an imbalance in positive and negative charges, while electric current is the flow of electrons, from one static body to another.

Walking on a wool carpet can cause the buildup of electrostatic charge on your body. When you touch a metal doorknob, the excess electrons from your body discharge to the knob, creating a static shock.
The shock is caused by the buildup of static electricity on the person's body as they walk across the carpet. When they touch the metal doorknob, the excess electrons on their body transfer to the knob, creating a sudden discharge of static electricity that is felt as a shock.
You feel a shock when you touch a metal door knob because of static electricity buildup on your body. When you touch the metal knob, the excess electrons on your body flow to the knob, creating a small electric discharge that you feel as a shock.
When you get a shock from a metal doorknob, it is an example of static electricity. This occurs when excess electrons build up on your body and discharge when you touch the metal doorknob, creating a sudden flow of electricity.
When you put your feet down and then touch the car when you get off, you will get a shock as your finger or hand almost touches the metal part of the car because you are grounded. The spark that jumps from the metal to your hand gives you the shock. The trick is to hold onto the metal part of a car and then get in. This way you won't be shocked because the electricity will flow over your body.
A static discharge. The friction from walking on the carpet builds up a static charge on your body, and when you touch the metal doorknob, the excess charge is quickly released in the form of a static discharge, creating a shock.
You can discharge static electricity from your body by touching a grounded object like a metal doorknob or faucet. You can also minimize static buildup by wearing natural fibers, using a humidifier, and avoiding activities that generate static electricity.
When you get shocked from a metal doorknob, you are experiencing static electricity. This occurs when an imbalance of electric charges builds up on the doorknob and your body, and discharges when you touch the doorknob.
To get rid of static electricity in your body, you can touch a metal object like a doorknob or a faucet to discharge the built-up charge. You can also try wearing fabrics like cotton or silk that are less likely to generate static. Additionally, using a humidifier in your home can help reduce static electricity buildup.
When walking on a new carpet, electrons from the carpet may transfer to your body, making you negatively charged. When you touch a metal object, the excess electrons will move to the metal to equalize the charge, resulting in a static discharge.
