[sdiy] Which 1/4" Jack?

[Oakley Sound]

Florian > There are some jack forms, which do not open the switch of the 
pin contact. Since the switch contact is connected to ground the input 
was shortened.

This is interesting. I have had no problem with any Switchcraft sockets 
or plugs.

But if Speck used the 112APC printed circuit board mounted sockets it is 
imperative that a largish hole be placed in the PCB to allow the tip of 
some longer plugs to poke through. Some plugs are too long and will 
touch the PCB and therefore not push in far enough and not break the NC 
contact.

I have seen at least one commercial product where the makers didn't put 
that hole there and any inserted jacks would leave the NC connection 
closed thus shorting out the tip.

In this instance its worth using the blunt nosed jack plugs which mostly 
come from the European and US makers.
