switches - Can you clarify what an 1NO1NC switch is
NO = Normally open (open = open circuit = not creating a path for the current) NC = Normally closed (closed = short circuit = creating a path for the current) C = Common (The drawings show the state in the absence of force.) When you press a normally-open pushbutton, you provide a path for the current.
