Circuits and Switches—Construction
Directions 1) Cut an approximately 1x3 foot piece of plywood 2) Divide the plywood into three sections 3) Arrange the switches on the board and fasten them down (see diagrams and pictures below) 4) Nails may be inserted where appropriate on the board to help secure the wires 5) Wire from the power source to the appropriate screw ports on the switches, among the switches, through the LED, and back to the power source (see diagrams and pictures below) 6) Connect all of the negative ends of the wires together, and connect them to the negative side of the power source (depending on the power source, you may have to add resistors to make sure you don’t blow out the LEDs—match voltages) 7) Connect all of the positive ends of the wires together, and connect them to the positive side of the power source 8) Cover all exposed wires with wiring tape for safety 9) Test your circuits to ensure that everything works properly (a flip of ANY switch should alternate the LED in that circuit between off and on) |

Budget Switches SPST (1) SPDT (4) DPDT (1) Total = 6 x approx. $2.50 each = $15 20’ copper wire = $10 LEDs (3) = $4.50 TOTAL = $29.50* *Price for the power source depends on what type you use. The circuits can be battery powered, but we used a spare cell phone charger. If you do this, you may have to add resistors to the power source to ensure that it doesn’t overpower the LEDs*
