[QUOTE="Doris, post: 117072, member: 4049"] providing the 'external influence' in this case is the discharge,low pressure or fault in the fire tec system - I'm confused now!! I've opted for the N/O switch - soley based on the info posted here, however, I find this confusing as, as far as I understood switches, this is my understanding..... [b]N/C[/b] (normally closed) would make a curcuit - therefore keeping an LED lit under NORMAL conditions.If there was external influence (discharge,low pressure etc) the switch would open and stop the flow of current to the green led, thereby advising of an issue with the firetec system. [b]NO[/b] (normally open) would not make a curcuit under normal conditions, only when tripped (by external influence = low pressure, discharge etc) would the switch close, make the curcuit and light the Red lamp!!?? -have I missed something? -Am I right in thinking, a switch will be making a curcuit, allowing current to flow when 'closed' ?
