Switched outlets are a versatile improvement for any space, enabling better control over electrical flow. Connected to a switch on the wall, they allow users to turn the power supply on or off quickly. This convenience controls lighting, fans, and other household gadgets without unplugging each time. It is beneficial when creating a specific mood through lighting variations, which is key, or turning off devices without reaching behind heavy furniture is preferred. 

GFCI outlets, standing for Ground Fault Circuit Interrupters, act as indispensable defense mechanisms against electrical shocks. They are engineered to scrutinize the flow of electricity between the hot and neutral paths and intervene instantly by cutting off power whenever an imbalance occurs. This swift action, occurring within milliseconds, is crucial in preventing hazardous shocks. They are especially vital in locations with high exposure to water, including kitchens, bathrooms, garages, and outdoor settings, which are more susceptible to ground faults. Distinguishable by their unique "Test" and "Reset" buttons, GFCI outlets are mandated by the National Electrical Code for inclusion in new constructions and during major renovations to improve electrical safety standards.
