Switches
The PCB was designed so that 3 single pole switches will fit easily in the enclosure. There is a special
gap made in the PCB which will fit almost all types of miniature single pole switches. There are a lot
of configurations possible, and you are free to experiment. By default you can use this configuration:
In this configuration,
SW2
(caps) is not installed. You could use a small internal SP3DT switch (ON-
OFF-ON), make a 3pin header with a shunt like in the picture or hardwire it. There are other
configurations possible like this one:
Note that there is little room between the potentiometers and when trying to fit a DP3T between
them you cannot use the optional plastic cases on the potentiometers. Fit before you decide!
There are different types of DP3T On-Z-On switches. Check which contacts connect in the middle
position and change the wiring if it is not to your liking!
