Electronic timer with photosensor
First Claim
1. A switch for turning on and off an electrical device, said switch comprising:
- a control module comprising a time module and an electrical output connectable to an electrical device, said time module comprising a clock programmable for disconnecting power to the electrical device at a set-off time; and
a light sensor module wirelessly connected to said control module and transmitting a light sensor signal to said control module based on light level, said control module adapted to provide power to the electrical output when the light module indicates the light level is below a threshold level and the time is before the set-off time, thereby providing power to an electrical device connected to said electrical output.

Abstract
A switch and method are provided for turning on and off an electrical device. The switch includes a control module, having a time module and an electrical output to which an electrical device can be connected. The time module includes a clock which is programmable to disconnect power to the electrical device at a set-off time. A light sensor is operatively associated with the control module and transmits a light signal to the control module based on light level. The control module is adapted to provide power to the electrical output when the light module indicates that the light level is below a threshold level and the time is before the set-off time thereby providing power to an electrical device connected to the electrical output.

21. A method for turning on an electrical device when lighting conditions fall below a threshold level and off at a set off-time, said method comprising:
-
connecting an electrical device to a timer module;
providing a light sensor operatively associated with the timer module;
