Some medical conditions like Downes Syndrome & ASD can make like switches irresistible to flick on and off. The ‘flickers’ themselves enjoy this, but it can be very irritating and stressful to others in the room.
I was asked to design a solution for the child of a friend of mine and it was a huge success. They all have a far more pleasant experience in the living room. The cover guard fits over the fitted light switch plate and the screws are reused – so no need to rewire or even go near the wires. The opening in the cover guard only allows for the key fob to fit into the arc and the rest of the household can uses these to turn the lights on and off.
