WebAn NPN output would go between ground and resistor. I'm saying this because I'm unsure about what you are saying in your comment. I think you need to be clear about what you do understand and don't understand. The same circuit suits either PNP or NPN. A dry contact can replace PNP or NPN but you need a power rail for a dry contact. \$\endgroup\$ http://www.learningaboutelectronics.com/Articles/Difference-between-a-NPN-and-a-PNP-transistor
