Last question on this thing--I promise. I am wiring 4 of these between my PH180 bricks and my TIUs. I want them to be manually reset. So I need to add a switch at J7 across pins 1 and 2. I was wanting to add a MOMENTARY pushbutton type from my parts stash. But I have several kinds of switches available and that got me confused.
My understanding is that the switch across pins 1 and 2 of J7 should be normally closed. When the button is pushed, that breaks the link between 1 and 2 which resets the PSX1. Then the button is released and the link is closed leaving the PSX1 active and ready to interrupt another short.
So that moment when I push the button, it breaks the connection between pins 1 and 2. That resets the PSX1. I release the button and the pins are connected again.
Is that what I want? The instructions make mention of using a SPST toggle switch. If that was used, and the toggle is in the closed position, flipping the switch leaves it open and the PSX1 resets BUT if the toggle is left open, then the PSX is in auto-reset mode so the toggle has to be manually flipped closed after the PSX1 resets. So that makes me think I don't want a toggle switch.
Is this right?
