Normally-open and Normally-closed Switch Contacts
Here, a normal condition is a condition when the switch is not energized manually or electrically. Normally open condition means the contact of the switch is in an open position when it is not energized. In a similar way, the normally close condition means the switch is in the close position when there is no force on its actuator.

A switch is essentially just a small cut in a circuit, that can easily be closed (to form a complete circuit ), or opened (to form an incomplete circuit). These positions are indicated on circuit diagrams as follows: Because current can flow in a complete circuit, we say the circuit is "on" when the switch is closed, and "off" when the switch ...

Light Switch On Off Position: Understanding Light Switches
Light switches play an important role in completing the electrical circuit that powers your fixtures. When the switch, specifically a switch that controls the light, is in the ''ON'' position, it allows electricity to flow through, illuminating your space. Conversely, in the ''OFF'' position, the circuit is broken, and the light goes out.
