Signal relay

brianqq · 17th November 2011, 04:01 PM

I am building a three channel guitar amp, and am having trouble selecting
a good signal relay. I will be using three SPST (preferable 5v)
and two DPDT (16v) relays.
Any advice?

Sounds like you want relays that are powered/switched by 5 volts. We need to know how much voltage and current you are going to switch. For a good overview of relay types check out this page. http://www.surplussales.com/Relays/sealed_pc.html

I am quite happy with these ones:

They are available in various coil voltage ratings.

The SPST are comming of the guitar input jack.

The DPDT will never see more than 800mv

At work we mostly use Axicom, Omron and Zettler (and some others). Only Omron has given us some quality issues over the years (actually enough for a customer to do a redesign).

For your application I'd recommend you check out the Axicom V23105 series, but any good quality relay should be suitable.

Ok.
On another subject, I need to find a toggle switch that won't pop when switching. I wire a mid pot bypass that works well except for the pop.

I have a lot of relays in stock

SPDT OMRON G5V-1 5V .99ea
SPDT OMRON G5V-1 12V .99ea
DPDT OMRON G5V-2 12V $1.50ea
DPDT OMRON G6A-234P-ST-US 5V $1.50ea

As for toggles I have them too but they do click.
