Hello All,

I'm trying to create a KiCad symbol for a salecom on-on-on double pole double throw toggle switch. I've done some research but I haven't found any definitive answers. Can someone help me out please?

Never heard of one.
I've heard of on-off-on switches but not on-on-on.
How does an on-on-on DPDT switch work?

 

The diagram is in the link he provided.

I'm not sure how to convey this in a schematic. I have seen switches like this in some pieces of instrumentation.

Okay.
Missed looking at the link.

That's more a DP triple-throw rather than a DPDT switch.

I think the symbol below more or less shows that function:

 

I made a pretty messy Kicad symbol for a switch that's probably identical to yours. Here it is. I only really cared if it made sense to me when I created it, but hopefully it makes sense to others too:

That's about as clear as it can be in a compact symbol. I like it.

It has an extra middle position where one side of the switch goes one way and the other goes the other way. The two extreme positions are the same as a standard DPDT.

Okay.
But the symbol I posted shows the connections for the three positions without needing a table.

I didn't mean to criticize.

@JTEX 's symbol seems pretty clear without the table to me. Multi-section switches are often shown as groups of contacts with a dashed line showing the elements act together.

The table and illustration are from the datasheet of the actual part I used. I only included them to show how the Kicad symbol relates to that part, pin-for-pin.

Didn't take it as criticism, just a comment/opinion.

I wasn't familiar with the dash-line notation for such a switch, but if others understand that, them I'm okay with it.

I hooked up the switch to my bench DMM and used the continuity function. I connected the leads to pin 2 and 5. It worked as the connected terminals table. This is a good start thank you! Question did you create a footprint also?

That type of switch is sometimes used to create a SPDT switch with make-before-break action, though usually the center position is not stable (i.e., doesn't have a detent to keep it there).

 

This is a 3 position switch with the contacts as shown in post #3. It's not that common, but they do exist.

The footprint will be the same as a DPDT switch of that size.

Here you go.

I have to say they're quite common in the world of electric guitars/basses and stompboxes. Can be used as a 3-way pickup selector, and also to switch a dual-coil pickup between coils in series, coils in parallel, and single coil.

Thansk!

 

Here you go.
