Reasons for a Light Switch Shock
A standard risk associated with light switches is that they are prone to electric shock.
Light switches are an integral part of our lives. The purpose of a light switch is to open or close an electric current to a light fixture or electrical device. Unfortunately, a standard risk associated with light switches is that they are prone to electric shock.
Several people feel a minor shock when they reach out for the light switch on the wall. A light switch can result in two types of shocks, static and electric. A static shock occurs due to the build-up of electricity on the skin and is usually harmless but uncomfortable. Transfer of static electricity when the finger touches the switch's metal screws results in a shock. Electric shock happens when there is an electrical leakage from the light switch, and it can turn fatal.
A light switch is a mechanical device that sees a lot of use throughout its lifespan. It can malfunction due to wear and tear. Experiencing several minor shocks or a painful shock requires calling in a certified electrician immediately to look into and fix the issue.
How a light switch can cause shock
Several reasons are responsible for a light switch shock. Some of these may include:
Defective light switch
A faulty outlet or switch usually results in shock. A light switch gets electric currents through a box, further connected to the wiring. If the light switch has a metal box that is improperly grounded, shocks may occur, as metal is a conductor of electricity. A light switch may leak electricity if the materials are poor conductors and insulants. Other factors such as loose screw or wiring, frayed wiring, or cracked casing may also lead to light switch shock.
Outdated switches
Outdated switches in old homes have two-prong without any protective ground wire, which increases the risk of any defects in the light switch becoming hazardous. The third wire in the modern three-prong switches acts as a safety barrier if there is an unstable electric current by allowing it a safe passage to the ground and preventing shock and electrocution. Call an electrician to replace all the outdated light switches in the home.
Damaged wiring
Damaged, loose, or frayed wiring can lead to shocks. Flickering lights, burning smell, smoke from the outlet, and warm-to-touch switches point to damaged wiring. Stop using the light switch and call an electrical contractor immediately to fix the issue.
Faulty appliances
Electrical appliances or devices are also a potential reason for light switch shocks. An appliance with broken cords, frayed wiring, and damaged circuitry causes the electrical current to become unstable, resulting in shock. Faulty appliances and devices fail to channel the electrical energy properly and are most likely to cause a shock when plugged into an outlet. A professional can inspect and perform the required repairs or suggest replacement.
Ways to prevent light switch shocks
To avoid light switch shocks, homeowners should:
Touch the switch with dry hands
Keep water away from the switches
Cover the outlet with a plastic casing
Use a humidifier
Use dryer sheets to wipe metal surfaces
Replace faulty switches
Purchase a static shock eliminator
Avoid wearing synthetic clothing
Call a local electrician for inspection if you are experiencing any issue with the light switch or other electrical components.
