Can You Smell Something Fishy?

A weird fishy type smell coming from a switch and/or wall socket is another unpleasant but common #electrical problem. This is often the result caused when an electrical device’s connection to the circuit is damaged, causing the electricity to jump through the air to complete the circuit. When this happens it can pass through anything that it encounters along the way and could potentially cause a fire if left unchecked.
