The installation of this is fairly straight forward but you'll need to use slightly longer screws than the ones that are currently attaching your light switch cover. 6-32 x 1 inch machine screws with a round head should work fine.

1- Slide the “RAIL-GEAR” into the “BASE-PLATE”.

2 - Insert the “KEY” in the “RAIL-GEAR”, it should fit snuggly into it.

3 - Remove the screws from the existing light switch cover. (You can either keep the cover in place or remove it.)

4 - Screw the “BASE-PLATE” over the light switch. You'll need to slide the “RAIL-GEAR” up or down to gain access to the screws. Validate that the “RAIL-GEAR” still slides easily, if not try loosening up the screws a little bit.

5 - Install the “COVER-PLATE” over the “BASE-PLATE”.

6 - Glue the 3 parts for the lever together (Gear/Handle/Wood)

7 - To install the lever, place “RAIL-GEAR” and Lever in the neutral/middle position then use the Pin and Clip to secure it in place.
