trimmer/pot question

[miro.toff]

HI!

 

I am searchin for that Potentiometers that

''when you turn them'' they clicks, cause i have some presets like A - B - C - D- E - F

and need that when i switch between them and select one, It is hard to move the knob acidentally.

 

thank you

You maybe could use Lorlin type Rotary switches and solder resistors between the terminals, to make a stepped attenuator.

What NorthernLightX said. However, a question I have... :)

 

It would be cool to know what u are using it for, more spesific, what you are connecting it to... Sometimes people confuses a potmeter with everything that looks like one, and it is really not a potmeter - it can be either a potmeter, a rotary switch or maybe rotary encoder, these three can look very similar on the surface, but in reality they are very different from each other.

 

Just making sure you know that it really is a potmeter you want, and not a simple switch.

 

But if you need to switch between 6 different resistances (measured in Ohm) the approach suggested by NorthernLightX is very good,

 

This might, if you already know about the basics of electronics , seem like stupid questions from my end. In that case - I didn't mean it that way ;) - just making sure we can help you the right way by determing what you know and what you are building :).

 

Have a nice day!

show a video where you can see a Man that turning a pot and you can hear a ''click grip''.

Thats what i searchin' for.

 

Thank.

Hi miro,

I have exactly such a rotary switch. It has 8 switching positions and 8 pins.

Every single position toggles between a pair of pins. Unfortunately i dont have a datasheet.

You you can have it if you want.

Best regards

Wondering about it,

it seems that the knob in question haven't 8 fixed positions, it can be turned 360 degrees but it ''click'' when turned.

Could be?

It seem like the guy in the video, have some difficult to rotate it.

The rotary switch in the video could be used in a digital circuitry or only analog one?

 

Thanks

I am that guy...

I dont really understand what you mean.

You can use that switch in every circuit.

It is like you have 8 single switches but you can turn on only one simultaneously.

[miro.toff]

I mean that; if it can process digital signals (10001, 00100, 01002 ) low voltage

or a high voltage can pass trough it ( 0 to 50 volt ).

Anyway thank you, is not what I am searchin' for.

Any other link?

 

bye.

OK I'll bite.  Here is a link that shows some rotary switches to pick from.  We still don't understand what type of signals this switch is connected too.  Is it an audio signal? If not, now much voltage and current is the switch going to control?  How many positions does this switch need?  Did you know that a rotary switch is not the same thing as a trim pot?
