Has anyone ever created an electrical switcher that *mechanically*
allows one to switch between appliances that run on standard household
current?(ie: TVs, stereo, computer, ect).

If not, can I get ideas on what it would take to build something like
it?

Thanks a lot.

Ok, I was actually looking for something you can plug everything into.
But I guess that is as close as I can get.

In a related project I'll need to be able to switch between four(or
more) rows of 56 pin circuits that will only carry voltages in the
area of +5V, -5V, +12V, -12V per pin.

In other words, I'll need to be able to switch from one row of 56 pins
to the next row in a "break before make" fashion.

I know there is nothing like this on the market, but I was wondering
if anyone tried any simular projects.

Thanks.

There used to be what were called "T-Bar" relays which were form C
and could switch up to, as I recall, 64 SPDT points per relay.

Two of those and a little logic would have gotten you what you were
looking for, as far as the switching goes.

But what are you _really_ looking for?

You've stated the voltages you want to switch, but what about the
currents?

I've never heard of those before and need to find documentation on
them.

Is a T-bar relay 100% mechanical in operation? It's only job would be
to redirected the current.

The AC will be taken care of by the Tap Switch, and will be done in
such a way that the AC is cut first *before* the present 56-row is
disconnected.

And the next 56-row will have to reconnect *before* the next AC
current direction is established.

AC = off / 56-row disconnected. Next 56-row connected / AC = on.

Thanks.

Ok. It looks as though I'll just have to design and build what I need.
