Latching Relay Switching

[JazzGuitarGimp]

While the info contained in the above posts will surely work, I like simplicity!

In looking for options to use on a new build, I ran across these! There are other configurations available, but the combination of NO+NC controls on a single chip looks ideal for amp use. Also, they are no more expensive than standard relays. And, I have found a simple 6VDC supply with a dropping resistor to the LED control pins works well.

This looks like a nice solution, if it weren't for the price. You need two of these to implement a DPDT relay. At Mouser's pricing, that will set you back $10.82. I am fond of the ADG333A, which is a quad SPDT analog switch (two DPDT relays) which still isn't cheap at $6.57 (Digi-Key). But you'd need four of the Optomos relays to do what this chip does, so $21.64 vs. $6.57.

Can't argue the price. But I'd rather spend the money for that relay and a DIP socket than spend the time to piece together a half dozen components
(per relay) to achieve the same thing. I value the simplicity! And in the totality of costs to build an amp, the percentage of additional $$ to go this route would be very small.

But, each of us on this site do things differently, and trade ideas. I was only suggesting another way to go!

Everyone have fun!

And to be fair, my point of reference for price is some stomp box designs I've done recently. Compared to amp building, pedals have a much smaller target price, so you've got to be very careful about unit material cost.
