+
+<p>
+This example illustrates how a timed switch can be used to drive a transistor. As the switch toggles at a set frequency, it alternately activates and deactivates the transistor. This switching action controls the current flowing through the collector resistor, allowing the transistor to function as an electronic switch. A voltage probe placed at the collector displays the resulting output waveform.

+<p>
+  The simulation shows the voltage at the transistor's collector.
+  When the switch is closed, current flows into the base, turning the
+  transistor on. This pulls the collector voltage close to 0V. When the switch
+  is open, the transistor turns off, and the collector voltage rises to 5V.
