Light Bulbs
June 23rd, 2010
How can I run two electronics or light bulbs on one switch?
See I have two electronics but for the two electronics I will use the example of two light bulbs.
I want to have two light bulbs that I want to run on one Single switch.
In other words I want light bulb 1 to turn on when i flick the switch to the left and the 2nd bulb to turn on when I flick the switch to the right.
So when I flick the switch to one side I want the other bulb to turn off and when I flick it to the other side the other bulb should turn off.
Thanks
Thanks
you need a double pole, double throw, center off switch.
wire the input voltage to the center pole
“lamp 1″ to the bottom or side 2
“lamp 2) to the top or side 1
This way, when the switch is thrown to the top, the BOTTOM is connected and when the switch is thrown down, the TOP is on…. the throw (toggle) is away from the connected sides.
where to find DPDT Center OFF switches at online stores such as;
