---I use these switches all the time but you usually have to add
electronic switches and diode logic or regular CMOS to get the three
functions. For example, our Dual Filter uses these switches to select LP,
BP, HP outputs at the single output jacks. MAX365 elements actually switch
the audio on the PCB with two diodes and a 100K pull down for logic.
