kit-kat clock style light switch cover plate, for a single gang toggle style. Please ask for assistance if not comfortable changing light switch cover plates, place the hole of the tail onto the pin located at the base of the switch cover, then keep it vertical to make sure it wont fall off while installing. then tightne the screws only until the plate cover doesnt move. Do not over tighten. then you can flick the tail and it will rock back and forth.
