In most instances you can manually control electronics in your home and office. When you are going to be out, you can just switch off a desk lamp on your way out the door. There are plenty of times when it can help to have an automatic system in place to control the power to various appliances. Holiday lights, for example, are often left on too long because the homeowner forgets to cut the power when they go to bed. Using an Ingraham digital timer provides more control and saves time and money.
