This is a cover for single switches, designed to fit standard switch cover sizes. It increases the pressing area, making it easier to push the switch. Installation is simple: just attach it with the included double-sided tape, and you can use it right away. It can also be removed, so it's suitable for rentals. (While replacing switches with larger ones like those from Panasonic requires a licensed electrician, this allows you to easily update your switches.) Quantity: 4 sets Color: White Compatible Size (Original Switch Cover): Approximately 120mm (H) x 70mm (W) Enlarged Cover Size: Approximately 127mm (H) x 81mm (W) *To remove, simply pull it off slowly. Heating it with a hairdryer will make it easier to remove, but do not exceed 60 degrees Celsius.
