Hello,

I found some interesting rotary switch with on/off at first click then linear potentiometer.

But I'm looking for something with on/off a the beginning and 5-6 clicks (positions) to choose menu on  a Analogic entry. I want each click to let the device On and not turn it off.

I d' like a push fonction too to select the menu.

Do you know a switch like this ?

Thanks a lot.

That would just be a rotary switch then. What it does is up to you as to how you wire it up and how your code interacts with it.

Something like this https://uk.farnell.com/lorlin/ck1035/switch-2-pole-6-pos-0-15a-250v/dp/1123691

I bet you didn't, I have never seen one of those, only ones with a log pot. They are used as volume controls for portable radios.

Thanks,

But It seems to me that it's not possible to have the first pin on ground (for off) ans the 4 other ones on Vcc and the analogic pin of arduino ?
Don't you think my chip is not going to turn off at each click ?

Could you show me a scheme with your rotaty switch please ?

Thanks.

Btw,
 are a lot linear pots dith on/off
For example :

I doubt it!

Actually, very unlikely indeed.

Because they are almost always being used for volume controls, and volume controls do not use linear potentiometers.

There are hundreds of variations of rotary switches, decide what you want, and most likely you will find it, but you need to search it out. Many sites have parametric searches, which may speed up the search process

fwiw, Farnell also sell these - make your own https://www.nsfcontrols.co.uk/our-products/switches/rotary-wafer-switches/

There used to be lower priced version which iirc was named 'make-a-switch' , or buy a couple or more cheap wafer switches and dismantle/rebuild or otherwise couple together.

if you can't pind one with a push switch, then mount the rotary switch in a flexible manner, with a push button behind it, That can be a bit of mechanical engineering :)

No, because your explanation of what you want to do is not clear enough to show you how to do it.

For example :
Well Amazon are famous for having sellers who don't know what they are selling. Looking at the comments from people who used the product to successfully repair radios it sounds like it was a log pot, because a linear pot would have been awful in such a repair.

Analogic is not a word.

If you want analogue (but not clicking) the the alibaba link could help.
