I am looking to changing some of the light switches at my church to push button timer switches to prevent the lights being left on.
Some of the rooms have 3 switches for 3 lights but I only want 1 button?
Any idea?

If you have 3 switches and they each operate just one light your will not get one button to operate them all, not without pulling an additional wire to each switch box back to your new main switch. Why not consider a motion sensor switch for each light. They turn ON when there is movement in the room and OFF when no motion is sensed after a certain time. http://www.google.com/products/catal...d=0CHcQ8gIwAQ#
