Transistor Switch Circuit 2.

This circuit uses a relay to activate the load (a light bulb).

Use the Switch on the left to activate/deactivate the relay via the transistor.

Notice the diode used to avoid damage to the transistor when the load is deactivated and the relay's magnetic field collapses.
