Unless I've misread the mini-pcb tracery , the boost switch is DPDT
using 2 seriesed switch actions for increased unreliability?
I would have paralleled for increased reliability of a simple switch
action if using a DPDT perhaps because it is more mechanically robust
than SPST or SPDT, or am I missing something?





That's not the Series/Parallel switch you are looking at?


Gareth.

Not my intended meaning, only 4 terminals are used of the 6 , but not in
a DPST sense as 2 of those 4 terminals are bridged across by a trace, so
the action is just a simple SPST, via 2 switch contacts. So one pole
on or off to simply switch in/out a filter cap or something
