WebNormally open switches make an open circuit in it's "normal" or default configuration. While, a normally closed switch is the opposite wherein a closed circuit is the default configuration of the switch. When a switch position is changed the two conductors are connected or disconnected for normally-open and normally-closed switches, respectively. A normally open switch is one that is open when not actuated. That means that, in its unactivated state, there is no path between the electrical contacts. When you push the button or flip the lever, it closes the circuit and completes the path, allowing current to flow .
