While I do use heavy duty Toggle Switch DPDT or DPDT in the past 35 years, I have never receive special training about connecting the wire over screw terminal.
DPDT / DPDT for general use can be found with soldering tabs too.
But for my latest project, all I could find was with screw terminals.
Plain human logic in use, toggle switch screw terminals these its best to be paired with solid copper wire.
But with multi-core wire:
And if you plan to get highest performance along connectivity perfection?
And if you care for easy way to replace an damaged toggle switch?
And if you do not wish to overheat switch body with 300C of soldering?
Then a new solution it should be used... Here is my answer which I came to this all alone, that is the use of fork-style shoe.
But there is a catch, you need to have stock of the one's with the appropriate dimensions.
Few samples that I did use at my DEMO presentation they are larger than needed only at center hole diameter.
The appropriate dimensions = 7mm wide / 3mm hole diameter.
