If you'd asked for a relay it would be more clear what were you asking for :-)))


I am using a Potter & Brumfield KUP-14A55-120 relay (3 Pole Double Throw):

Two of 3 poles I use to switch AC inverter or AC mains to my new power output (load).
This way the AC inverter out is never connected to the mains even with a single wire...

The third circuit of the relay is used to short the AC inverter ON/OFF switch to
automatically turn it ON when there is no mains power (idle relay position).
In order to do it I had to remove temporarly front face of the inverter box
and attach two wires directly to the inverter's ON/OFF switch...

The relay has a transparent plastic flange type case to easily screw it to the interior
wall of my wooden tank stand with regular wood screws. It has electrical connections
of "quick-connect" type, so wiring is easy after you crimp standard female quick
connectors at the wire ends.

How have you wired your DPDT relay ? You have only 2 pairs of contacts...
Also, have you got some kind of socket for it ?

Anyways, thanks for figuring that out. Yes, that's what I wanted.
