[disclaimer: I didn't want to start a new thread for this so new members have a single thread to read if interested in a replacement relay.]

Hi guys, I'm pretty new to all this, and electronics in general. I was wondering if a solid state relay would work. The reason I ask is the silence of the switching would be very nice. :)

Thanks,
TheGooch

Mechanical relays are slow and wear out. I went to
DPDT relays and RS (the shack) has them cheap.
SS (solid state) would be sweet and fast, and last
much longer. If being wired up to self-interrupt is
not destructive to the relay...

I'm sure their must be a way.

The advantage to mechanical switching is how abruptly it switches off, going solid state may reduce the size of the spike a little but you will gain in the frequency you use.

That digi-key part is mechanical as far as I can tell.
It would need "modded" too, like the IRO relay.
U need a SPDT or DPDT. Here is my suggestion:

RS Part Numbers for DPDT
Relay: 275-218 (or 275-217, check compatibility)
Socket: 275-220A

Use the socket and it makes an easy R&R for the bad relay!
And they WILL wear out. But using the double contacts, it
could possible last 2 to 4 times longer than a single contact
and way longer than the "modded" contact in the original IRO.
