Power Jack with Added switches
|This is the same Power Jack meant for use with our 12V 1Amp or 2Amp power adapters OR our 3V 1 Amp or 2 Amp Adpater |
This is an easy unit to use: the switches are already attached to the power jack.
We can add any number switches, in the above example there are 4 of the on/off switches attached to the jack.
The advantage of having a switch added, you do not have to plug/unplug the power, and you can individually control the LEDs in your project.
Multiple switches gives more control over the areas in a project. Consider 1 switch for the first floor one for the second floor. Or 1 switch for the first diorama section, one for the next section, etc.
How to attach your LEDs to this unit?
All reds wires from all of the LEDs will go to the red wire coming from the power supply. It is ok if the red wires from the lights first go to hook up wire(s) and then to the Red from the power jack.
The only difference in the next step is the black wires.
You are going to group black wires according to the zones of your project, example:
- The black wires from the first floor go together to the First Switch.
- The black wires from the second floor lights go to the Second Switch.
- The blacks from the outside lights go to the Third Switch, etc.
Each switch controls a certain number of LEDs, depending on the black wires!
The switches are 1 Amp. So each switch can control up to 50 LEDs. LEDs are 20 milliamp.
Remember to shrink tube all connections to prevent shorts!
