⚡ DC Motor Switch Machine Experiment – Easy Idea

🔧 Concept

Use a small DC motor + cam or lever to create an automatic ON/OFF switch machine.
When the motor rotates, it presses a switch to turn a light ON or OFF automatically.


---

✅ Materials Needed

Small DC motor (3–12V)

Cardboard or ice-cream stick

Small plastic bottle cap (for cam)

DC switch or micro-switch

9V battery or mobile charger

LED light or small bulb

Glue gun / tape

Wires



---

⚙️ How It Works

1. Attach a bottle cap off-center to the shaft of the DC motor (this becomes a cam).


2. Mount a switch next to it.


3. When the motor rotates, the cam pushes the switch at every rotation.


4. This turns ON/OFF a light or buzzer repeatedly → looks like a machine switch system.

🛠️ Steps

1. Make the cam

Take a small bottle cap.

Make a hole slightly off-center.

Fix it onto the DC motor shaft.


2. Build the switch stand

Use cardboard to make a small tower.

Attach your switch or micro-switch on top.


3. Position the motor

Place the DC motor so the rotating cap touches the switch.


4. Connect the circuit

Battery → Switch → LED → Back to battery.

Motor connected directly to battery.


5. Test it

When motor rotates:

The cap pushes the switch → light ON

Then release → light OFF


Creates a machine-style clicking switch.

🌟 What You Can Show in the Video

Demo slow-motion of the cam pressing switch

Show light blinking fast

Explain “automatic switch mechanism like in old machines”

Measure speed using a marker on the cap

🔥 Bonus Idea: Dual Switch Machine

Use two cams on the same motor
→ one press switch A
→ second press switch B
This makes a dual switching system, good for DJ lights or alarms.
