Create more advanced signal switching with a basic ON-OFF-ON switch😋.

  • Please play the switch.
  • Notice the three positions: left signal, mix of both, right signal.

Simple smart switch ​

  • Please play with the three positions of the switch and notice the three different signals on the output.
  • Notice that the circuit plays with the difference in resistance between the two signals connected to the switch and the third below the switch.
  • When the square or triangle wave is selected in the summing mixer, it completely overpowers the sine wave, reducing it to zero.
  • I added two buffers between the switch and square and triangle because it is important that these signal outputs have a very low resistance / impedance at the summing node.
