Hi

What switch do i need for this function please? I ordered some 3dpt (on-on-on) switches but can't find a way to make them work so I expect I misunderstood what I needed to buy.

Thanks

 

hi oramics,
Welcome to AAC.
What is part number of the switches you bought, or a link.?

Hi Eric, thanks

• RS Stock No. 734-7053

A double-pole, double-throw (DPDT) switch will do that. So will a rotary switch.

Edit: The RS switch is DPDT and should work.

EDIT2: I don't believe it will work. You need a 3-position grid switch according to Google. https://www.diynot.com/diy/threads/3-position-grid-switch.147315/

 

hi oramics,
I have used a similar type, exactly what switching action do want in your circuit.?

Hi

I want a switch to select between three inputs, line, mic and piezo with a single output going to a biasing op amp stage.

 

hi,.
A rotary 3 to 1 switch and knob would be a simple option.

Thanks.

I did look at this originally but couldn't find one that wasn't expensive. But now I think about it I remember there being some rotary switches that have a selector tab to choose how many positions the switch is. It's been quite a while but think this is the one I've used before. rotary switch

 

hi o.
This is the data sheet and a clip stating that a stop can be added to get the required number of switch steps.
E
BTW: choose the 'non shorting ' type

 

What switch type do you want?

Rotary

Slide

Ganged push buttons

Electronic analog switch IC

Also, how many outputs? 1 (mono), 2 (stereo), more?

Hi AK

Ideally it would be a toggle switch for smaller footprint.

1 mono output.

Thanks Eric, I'll order those if a toggle isn't an option. I spent ages being confused by that datasheet before you replied!

 

hi o,
Look here for one option.

Thanks. I realised I have 3 of them Lorlin switches in one of my projects, so testing it it does what I need. Toooo many projects to remember whats where! Thanks.

 

I was just about to post that what you need is a single-pole, triple-throw toggle switch. You can find pictures and even eBay listings for them, but nothing that is real. Rotary is probably the only way.
