I am looking for a solid state replacement for the Atlas #200 Snap Relay (double pole, double throw) or a latching relay equivalent that can be operated with DS-64 output. I have several of these under the layout to control my scenery lighting. They are very loud operating and cause a distraction to visitors. I have done some searches on several popular electronics sites but am presented with hundreds of relay specs to look through. My bet is someone has a bead on exactly the relay I need. Thanks in advance if you could just point me in the right direction. Geoff
Don't know of any that are just a imple unit to hook up as a direct replacement. Don;t think you would actually find an electronic equivalent of a snap relay. A circuit driven off the DS64 set to the stall motor mode, maybe.
However - look at the Aux-Box. It is pretty much what you want. A DCC stationary decoder that can switch on and off high current loads, all solid state. No clicking relays.

Thanks, Randy, but I had looked at the Aux-Box before and found it to be really overkill at $100+ to control a couple of circuits. Perhaps "solid state" was too tight of a specification if even a quieter electromechanical equivalent could be found. I'll keep looking. Geoff
What you want are latching relays. I have a couple that I got at All Electronics, but that was some years ago and I have not seen them in their catalog in quite some time. You may have better luck on their website, but...
Maybe some of these will do, I did not check the specs on any of them.

LION builds his own latching relay. Actually it consists of two relays a 4PDT relay with a latching circuit on one of the poles and a second SPDT relay to break the latch circuit and release the main relay. Now you can work the main realy as if it were a latching relay.

Geoff,
I have excellent hearing. Out of the 45 snap relays that I have, used for frogs, panel lites and signals, I have yet to hear one. The undertable switch machines, I have you can hear them, but I want to. What do you have them mounted to, foam board? Mine are mounted to 1/2 ply, with 1/2 Homasote on top. I bought the snaps when they were 7.50, also never had one go bad, in 25yrs running. You might be able to find latching relays in bulk, at a surplus Electronic supplier. Do some simple Google searches.

I've also got a few latching relays. They have been in place for 7 or 8 years now with no problems.
I found that on mine, the polarity on the coils is important.

Instead of replacing the Atlas Snap relays, why not try covering them with something stuffed with sound deadening material.
