Hi I am just beginner Please help me connect between rotary 2 poles 6way and Digit Numeric Display. What I have to do? If anything I need to buy?

Thank you

What do you want to do?

You say you have a 2 pole 6 position switch.you have to be more specific

I think this is about the simplest, with passive components. A Binary-to-7 Segment decoder chip and a few diodes would also work.

Hi Ken
Thank thank you so much
can you tell me
What can of diodes i need to use ?
Zener diodes or signal diodes ?
and what about Resistor (for 5v)
i need to use
I am sorry I am just beginner but i want learn )
Thanks
Roby

The diodes can be common signal types, like 1N4148. The resistor values will depend somewhat on the Vf (forward voltage drop) of the LED digit. Not critical...somewhere between 120Ω and 330Ω. Figure: (4.4-Vf) / 0.02

For the digit, if you could only get a "common-anode" type, just reverse the polarity of all the diodes, and swap the +5V and common.
