Help: Electrical Switcher Project

Feb 10, 2008 6 Replies

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.

Thanks.
