How does a normally closed contact work?
A normally closed contact is a switch or relay contact that is closed by default and opens when activated. When no external force is applied, the contact is closed, allowing current to flow through the circuit. When the circuit is energized or activated, the contact opens, interrupting the flow of current.

What is the function of a contact switch for a door and how does it help in controlling access to a room or building?
A contact switch for a door is a device that detects when a door is opened or closed. It helps control access to a room or building by sending a signal to a security system or door lock when the door is opened or closed. This allows for monitoring and controlling who can enter or exit the room or building, enhancing security measures.
How much charge flowed through the switch when it was closed?
The amount of charge that flowed through the switch when it was closed depends on the current passing through it and the time it was closed for.
