SPDT on-on-on?

[rankot]

AFAIK, SP3T switches can be only made in this form:

https://il.rsdelivers.com/product/nkk-switches/ss14mbh2/pcb-slide-switch-sp3t-on-on-on-100-ma-side/1251865


or as rotary switches, like this:

Toggle switches CAN NOT be made in SP3T form, due to their construction.

This thread is slapstick.
Yes, we found out that SP3T switches exist and that dpdt on-on-on switches can be used.

I don't see how any of the SP3T's solve the op's problem.   He wants all three terminals to connect together in the middle position.

The DPDT on-on-on solution does solve the op's problem.  A fair-enough solution using off-the-shelf parts that's aren't too hard to find.

I still don't understand, why such a spdt on-on-on doesn't exist.

And the simple toggle switch in guitars wasn't invented for the Les Paul, it existed long before. So, at least there WAS a market for this functionality.

The LP switch is a good example of existence.   I suppose the function isn't something that comes up often.
In the middle position there's no bad consequences when you short two pickups together but your probably wouldn't want to do that with two power sources.  On the flip side to could have a single power source driving two loads (say lamps for example) and the middle position would be both on.

Ducks Arse suggested the C&K catalog.  The old C&K catalogues had all sort of weird arse switches.   Things that make you wonder why such a switch exists.    I have not checked if the LP type 3 position switch exists in there.

Sure, you can use a dpdt as mentioned, but it's bigger and it exists in two versions (one connects 1-2 and 5-6 in middle position, the other connects 2-3 and 4-5), which might be a source for mistakes.

And the simple toggle switch in guitars wasn't invented for the Les Paul, it existed long before. So, at least there WAS a market for this functionality.

They don't exist due to the form of a mechanical construction of a toggle switch, so it's only possible to make On-Off-Off or On-Off-On SPDT. If you need On-Both On-On, then you must wire DPDT as shown before, or you must use some of the differently constructed switches I mentioned above.

@rankot: That's the picture I was looking for. Thx!
