Simple non-digital input selector

[dhbiker]

Hi there

i know there are threads already about this but none of that threads answer my question.

i would like to switch between 4 inputs preferrably with relays.

any simple schemes availible ? (i'm a fan of KISS principle)

Use signal relays that work well at low current.

 

[dhbiker]

any reccomendations what relays should i take ?

 

[AndrewT]

google "signal relay" or Omron.

 

[dhbiker]

well i know how to google

i meant if there is any reccomendation about Brand/model that stands out maybe

 

[mickeymoose]

The Omron G6A-274P-ST series has an industry-standard pin-out and bifurcated contacts for reliable low-level signal switching. E

If you don't want to build one, here's one that I have used.

Looks like DSP relays...might be low current but not what I would call signal relays.

Relays to use:

IM relays (IM07 is 24V coil) are min 100uV

(mickeymoose)
G6A-274P-ST are min 10uA / 10mV min signal

G6K or G6S series are also min 10uA / 10mV min signal

Signal relays or Telecom relays are what to look for.

Look for low switching voltage in the data sheet.

mickeymoose and DUG thank you very much kind sirs really appreciate it

i rather DIY it and pay 4-5 times more than the chinese stuff. atleast i know what i have in the first place

What's different in posts 6 & 8 that got a "thank you", from post4 that you rubbished?

Then again, what do I know?
