For me to save electricity, When I’m not studying I will use the 10 watt light in my room. The problem is when I want to study my homework, the 10 watts is not sufficient enough to illuminate my vision. So I installed another 20 watts fluorescent light to have a brighter radiance. Im just wondering, if there such a switch that can control the two lights one at a time. I tried to paste my diagram to further elaborate but it wont paste on this site.
110v (a) ---------------------->
on (for 10 watts light)
110v (b)----------------> off
on (for 20 watts light)
^
110v (a) -------------------------->^

It would probably be easiest to use two switches, however one could use a what is called a "double throw" switch if the wiring is accessible enough to make the connections . You would probably want a three position, center off toggle switch, or a rotary switch with an off position. Such a switch should be available as a lamp replacement part. You might even find from a lamp parts supplier, a switch that will switch in the sequence: off : a : b : a+b

Ask for a single pole, three position switch.
Example: Down for 10 Watts, all the way up for 20 Watts and off in the center.

There is a type of switch that will work in the way that you suggest, it is a very simple switch that can be switched up down and in the middle, you can get these switches at radioshack and they are really easy to install
