Is my switch/jack wiring right?

[carboncomp]

Hello, could someone with more skill then me check my wiring diagram.

It's supposed to be 3pdt input grounded with center negative DC jack.

But think I may have got confused with wiring the batter to the input ring (want it to only complete the battery circuit when the jack is plugged in).

the schematic looks right to me- ? is that what you mean?  the baterry neg. lead goes to the ring tab of input jack.  pos. lead goes to switched tab of your DC jack.

what I would say is that the battery NEG should go to the Input Jack Ring terminal.  In this case (not sure why) you are showing a switching TRS jack and the battery NEG is going ot the Input jack switched ring jack.  When the jack is inserted, the input jack ring will in fact make contact with its sleeve as you desire, but due to the battery NEG being wired to the switched ring terminal, it will not connect to the input ground.

So, should I jumper RN to R?

and are the + connection for the DC jack the right way round, so the battery disconnects with the DC plug in?

exactly what sort of jacks do you have to build with? the jacks in yr dia look like they are the plastic pcb types, with switches that all open when the plug inserts. instead of "RN", you want "R" ("T" and "S"). or short across each pair of contacts.

I have 6.35mm PCB Mounting Jack Socket (Normally closed switched)

So, I really just need to ignore the N lugs, as they only come into play when the jacls are removed from the socket? (or is it good practice to jumper them?)

Out of interest what dose the N stand for in RN/SN/TN?

Ring Normal, Sleeve Normal, Tip Normal.

"Normal" is the contact that comes into play when no plug is inserted. You can get "Normally Open" and "Normally Closed" switching jacks.

Your drawing shows normally closed jacks, the "N" connections will be broken when a plug is inserted. For example in your DC jack, with no adapter plugged in, 2 and 3 are shorted together and thus the battery + feeds the +9V connection. As mentioned above, battery - should go to R, not RN, because RN will be pushed open when a plug is inserted.

The typical stompbox plug-switching has nothing to do with switched jacks: the Sleeve of a TS plug shorts the Ring and Sleeve together on a TRS jack when it is inserted and this is what accomplishes the switching action. No plug = no connection from battery - to ground = no current path for the battery, in other words, "power off."

You've got the right plan for the DC jack: whenever a plug is inserted the effect is turned on, whether a plug is inserted or not, because the DC - goes straight to ground, no switching.
