The AutoChron wireless wall switch timer is a patented, easy to install timer that mounts over any standard toggle wall switch.  It will automatically turn on & off the toggle without requiring any hard wiring.

The timer's easy-to-program keypad offers a manual override allowing you to use your switch without affecting programming. Set the AutoChron to flip the switch on up to nine (9) times a day, remaining on for anywhere from one minute to 24 hours. It's as easy as setting an alarm clock.

Controls indoor lamps, lighting, ceiling fans, porch lights, landscape lighting, holiday lights - any device that is controlled by a wall switch.

Easily mounts directly on top of the wall switch plate with included mounting screw. Works on single plates, can be mounted on one toggle switch for double plates and can be mounted on the two end toggles with a 3-switch plate.

The AutoChron has a simple key-tap programming with an easy to read large LCD display. Multi-function display also has a low battery indicator, room temperture and glow in the dark buttons. Requires two (2) AA batteries (not included).

AutoChron saves you energy and money and provides peace of mind. Avoid the predictable "timer-controlled look" when your home is lit up.

Perfect for families with forgetful kids who leave their lights on in their room!

The AutoChron makes your light switch a genius.®
