Hello,
I've bought a bunch of voltage selectors made by Schurter, Switzerland, for less money. It allows for selecting one out of six possible mains voltages, given the mains transformer features a four section primary: A pair of ~100 V windings and another pair of ~20V windings. For details see the attached datasheet, please.
What voltages would you chose for the individual winding sections to cover as many actual mains voltages as possible? My idea would be two 110V and two 10V windings, allowing for 110-120-130-220-230-240V mains voltage. Is this appropriate and versatile enough?
As said above, the switches were from surplus, hence relativly cheap. The reason for this most probably was the writing: Mine are part # 0033.3501, the fist one in the list, and allow for 110-130-150-220-240-260 V when connected to a 2x110V+2x20V transformer, which isn't very useful. So, after having defined appropriate voltages (see above), I think to have someone make donut shaped stickers that I may stick onto the switches. As the angle between each pair of positions is 30°, I need to put the voltage numbers in a circular arrangement. Which CAD software is useful for this purpose?
TIA and best regards!

I saw it in some old cassette and radio
players of decades ago. But I really don't see DIY application unless you will trade your designs across the world.
As you say" "Best regards" 🙄

Check the Wikipedia "Mains electricity by country" table. Your proposal would only miss the 100V Japan system. If you plan to sell the device worldwide, you also need to be compliant to several safety standards.
No, surely I won't 😉 . It's just fun to have some gings and bells, isn't it?
Btw, after some reasoning I'd opt for each a pair of 115V and 5V windings, i. e. allowing for 115-120-125-230-235-240V. Thus I can fine tune to the actual mains voltage here.
But how to make the new labels?
Best regards!
