Absolutely, you need to ground the light switch. While the box may be grounded, the switch itself should also be grounded for optimal safety. This provides an additional layer of protection against electrical faults and can prevent potential shock hazards. Ensure that either the switch's ground screw is connected to the grounded metal box or directly to the ground wire. This will help ensure proper safety standards are met in your electrical setup.
