I wanted to ask how DPCO (double pole change over) relay is operated. From what I've read, it's also called DPTT (Double Pole Triple Throw). It's amazing that with a very small size and coil voltage rating of only 5Vdc, it can switch loads of up to 250Vac and 150watts according to the datasheets. It just seem impossible to me knowing that most SPDT and DPDT relays of the same coil rating can't do it.
So i wanna ask if with those given ratings, it can be used to simultaneously switch 2 electric fans, 220V 60watts each?
Another question: How is it operated/used? There are 3 contacts for 1 pole. With 1 contact normally closed, how can i switch the wiper to the 2nd contact? to the 3rd contact?
...thnx..
