Abstract: In accordance with one embodiment a device that fits and installs on top of a light switch comprising of: A Base plate holding a motor, a battery pack, a gear on the motor driving a rack with a gliding hammer arm connected to as part of the rack, which moves along with the rack when the motor gear turns in either direction along a guiding channel with a mechanical or a magnetic reed switch actuated by the rack pushing it or magnetically activating it using a reed switch and a magnet placed on the rack or the hammer in order to turn the device on and off with a motion sensor an audio alert device, an audio input device “microphone and a LED indicator. Accordingly several advantages in a number of aspects are as follow: The rack and gear approach eliminates complicated gear box which is both noisy and difficult to manually override. The hammer approach allows for the turn on and off of the light switch as light switch is normally used.
