Relay switching

[Nuts]

Hello,
I want to build true bypass relay looper that i could turn on and off by another pedal that will connect to it.
I found DPDT 9v relays at small bear.
are there any available relay looper schematics?

I want to put pedals that I'm running thorugh the effect loop, on the top of my amp, next to the relay looper,
and place the pedal that will control the looper on the floor.
is it possible ?
Thanks ,
Nuts.

Thank you very much !

Hey,
Can i use 9v relay insted of the 12v in this  
maybe by changing some parts values ?
I've alreay built it(with 9v relay), but the switch always stay in one posiotion.
The led turning on and off though

Remove the relay from the circuit and test the relay with a 9V battery on its own.

when i test the relay on its own with just a battery it works

You should be able to. Take a meter and measure the voltage across the relay coil when it should be on. I suspect that you're not turning the transistor on hard enough to put full voltage on the relay coil, maybe.

What voltage are you using for on/-off?

What voltage are you using for on/-off?

9v

Is it a latching relay?  Depending on the type of relay, if you are using a normal on/off stomp switch and it is a latching relay, you will get it staying in one position.  Also, is there a power polarity requirement for the relay?

so thats the problem, yea it says latching...

That is the only 9v DPDT relay i found.

Does anyone know any online store that sells 9v DPDT that isn't Latching ?

Thank you for the help.

There is a *latching* relay driver circuit at GEO, too.

I found these relays on ebay

It doesn't says latching, will it be good for me ?

[flo]

Looks good.
But the latching relay is also fine to use.
