I bought the following switches from automationdirect.com
Here are the switches
I was expecting them to work like ordinary sp switches only pushbutton with an led. But they came with a "contact block." The contact block is N.O or normally open. So I assume this means it's off and when I push the button in will be closed and power the devices.
I'm not sure about wiring, though. Can anyone offer some guidance on wiring or on what the contact block is and how this puppy works?
Many thanks. I was hoping to get a RIMS control panel going this weekend, run some tests and brew next weekend.
