When a switch is 'open' that means it is in the 'off' position. 'Closed' means 'on'.
The switch would be open.
The device is called a switch.
The effect of an open circuit is that no current will flow.
Closed. If it is open then the power is off.

An open circuit....
A light switch
A switch.
There is a complete path for the electricity to flow. The opposite of an open circuit. If a light switch is on and the light comes on, the circuit is closed. If the switch is turned off, the light goes off because the circuit is open.
If the switch is what is keeping the load from turning on, then yes, there is a voltage across the open switch.
When you turn on a light switch you do not have an open circuit.
It open and close it
the electrical circuit, load, conductor, open circuit, switch,
The switch would be open.
So that when the switch is in the open position the circuit is open and electricity cannot complete the circuit. When the switch is closed it completes the circuit and electricity flows completing the circuit and powering the device.
The device is called a switch.
The effect of an open circuit is that no current will flow.
