Do light switches have to be gRounded?

Yes, light switches should typically be grounded for safety reasons, especially in areas where moisture is present, such as bathrooms or kitchens. Grounding helps prevent electrical shock and reduces the risk of short circuits. However, some switches may not require grounding if they are designed for use in non-grounded circuits, but it's essential to follow local electrical codes and regulations. Always consult a qualified electrician for specific installations.
