I designed this device to time the operation of the 120V AC battery charger for my battery powered drill. I found out the hard way that the battery chargers for these batteries run HOT. If left plugged in all the time, they will burn out. These type chargers run $40.00 to $70.00. Yes, it is true that this charger will cost $30.00 to $40.00, But, it will not burn out. The timer is a spring wound timer. The timer is basically a switch that will stay on for the time set. This switch (timer) will carry an electrical load up to 1HP (745.6 Watts). I have never had a timer go bad, but if it did you can replace it for $20.00 or less. The battery charger for my 19V craftsman drill draws 65 watts.
If you send me your email address & you are a LJ & mention Timer I will email you, FREE, a PDF file that has easy to follow instructions to build this project.
NOTE: If you do not get your plans within one day, PLEASE send me another massage.
