Light Switch Servo Holder

This is my design of a light switch servo holder to automate the click of the switch.
This design works with the Niko light switch as shown in the image.

I used a 9g servo to simulate the click as they are cheap and easy to control.
There are 2 ordinary screws that hold the holder to the wall, and 2 small servo screws that hold the servo in place.

As barrier on the servo I used 2 standard servo connectors joint together with 2 servo screws as shown in the picture.

I currently use it with a Niko dual switch but a single switch can be used too.
