Potential Fire Risk From Wall Switches

Household electrical components are often overlooked. Wall Switch If there are design flaws or aging, an electric arc may occur the moment a plug is inserted, potentially causing an explosion or fire. When the plug makes poor contact with a switch or socket, even a tiny gap can become a pathway for current to jump, triggering a fire.

Several accident cases have demonstrated these hidden dangers. In one residence, a loose plug and unstable socket connection caused a high-temperature spark when electricity was applied, instantly igniting dust and flammable materials accumulated in a hidden part of the wall, leading to a fire.

Old switches and sockets are frequently used, and their internal metal clips may become loose or worn. Once the elasticity of the metal clips decreases, they cannot hold the plug firmly, causing the plug to easily come loose or tilt after insertion. In such cases, even a slight movement can trigger an electric arc.
