Build a Switch Circuit

Objective: Create a circuit that uses a switch to control an LED.

What You Need

• Copper tape or conductive tape

• A 3 mm LED

• A resistor

• A 3V coin battery

• A switch (you can use a metal paperclip or a pre-made switch)

• A template (like the one shown)

• Clear tape (optional for securing components)

Steps to Build the Circuit

1. Prepare the Template

• Place the provided template on a flat surface.

• Observe the labeled paths for the resistor, LED, switch, and battery.

2. Lay Down the Copper Tape

• Stick the copper tape along the orange lines of the template.

• Ensure the tape is smooth and has no gaps for proper current flow.

3. Attach the Resistor

• Locate the resistor section on the template.

• Secure the resistor across the labeled points using clear tape or fold the copper tape to hold it in place.

4. Install the LED

• Find the LED symbol on the template.

• Insert the LED with the long leg (positive) connected to the “+” path and the short leg (negative) connected to the “−” path.

5. Add the Switch

• Locate the switch section on the template.

• Place a metal paperclip or a pre-made switch in this area.

• Attach the paperclip or switch to the copper tape, allowing it to open and close the circuit.

6. Connect the Battery

• Place the battery in the designated circle.

• Ensure the positive (+) side of the battery aligns with the “+” on the template.

7. Complete and Test the Circuit

• Roll the template along the dotted line to complete the connection.

• Close the switch by pressing or sliding it into place. The LED should light up.

• Open the switch to break the circuit and turn off the LED.

Note:  print  out the circuit diagram using a blade/scissor by cutting it to make it usable as a breadboard template.
