AINSER64 isolate switches

Hey folks,

 

this is not the first time I run into this problem and I don’t have a solution for that. So… I’m asking here. Here is the situation:

 

I have an AINSER64. I want to plug three footswitches into the AINSER. I tried it like this:

 

5V o----/ ----o—|####|----o Ground

     |               |                     |
     |              ±— to A0      |

     |                                     |

5V o----/ ----o—|####|----o Ground

     |               |                     |  

     |               ±— to A1    |

     |                                     |

5V o----/ ----o—|####|----o Ground

                     |  

                    ±— to A2

 

Well, of course I run into the problem that A1 and A2 are triggered when just A0 is pressed. It’s also the case when I put jacks in every socket.

 

So my question is, how to isolate those sockets? Any tipps?

 

Thanks,

Chris

With suitable resistor values the switches shouldn’t influence each other.

Which values are you using?

These are 1k resistors.

That’s a bit on the low side - try something in the 10k range or higher.

Okay, 10k works perfect! Thanks!

 

Merry Christmas!

Going from 1k to 10k ohms doesn’t make sense to me.  I would have suggested going to 100 ohm if your problem was coupling between wires.  I wonder if your problem was a missing ground wire going to your resistors.
