Dual voltage-controlled SPDT switch (2HP)

A simple but versatile module that routes its common input/output to one of two output/inputs. When a positive voltage is applied to SEL, the connection into the COM jack switches from the middle ('normally closed') jack to the bottom ('normally open') and the LED lights up. These connections are bidirectional, so you can switch one input between two outputs, or between two inputs into a single output. Works even at audio rates and beyond, you can use this to reroute CV or trigger sequences, splice wave shapes, and so much more!

The SEL input is connected to a Schmitt trigger, so any kind of (positive-going) signal can be used to reliably trigger the switch.
