Using these switch plates is easy. Just replace your old switch plate with the new MacKenzie - Childs one. Make sure to turn off the power before installation to avoid any electrical hazards. Since these are handmade products, each piece has its own charm and minor differences, so don't be surprised if yours looks a bit different from others. To maintain them, simply wipe with a soft, dry cloth regularly. Avoid using harsh chemicals as they may damage the hand - painted finish or the antique - brass - plated hardware.
