In a circuit, the line connection carries the electrical current from the power source to the light switch, while the load connection carries the current from the light switch to the light fixture. The line connection is typically connected to the hot wire, while the load connection is connected to the wire that leads to the light fixture.

A single pole switch controls one circuit, while a double pole switch controls two separate circuits.
A 4-wire switch functions in a circuit by allowing the user to control the flow of electricity through four different connections. The switch can be used to open or close the circuit, turning the power on or off to the connected devices.
In a light switch circuit, the line is the wire that brings power into the switch, while the load is the wire that carries power from the switch to the light fixture. The line wire is typically connected to the power source, while the load wire is connected to the light fixture.

An NPN or sinking output accepts voltage and sinks it to ground to complete the circuit. A PNP or sourcing output sources voltage and the external circuit sinks it to ground to complete the circuit. A sourcing circuit would be drawn as voltage->switch->load->ground. A sinking circuit would be drawn as Voltage->load->switch->ground. In these cases, the switch could be a transistor.
When a switch is open (wires not connected) it is considered off. When a switch is closed it is considered on. If you move a switch and the wires are not connected the the circuit is open and current cannot run throughout the circuit to power the device.

Its means there is no continuity between point Ato point B. Ex. A light switch : When the switch is off it opens the circuit and electricity does not get to the light, when the switch is on the circuit is closed and the light will turn on.
In an open circuit no cuttent can flow so the switch would have to be in the off position- the switch is open and not completing the circuit. A closed circuit is one where current can flow all the way through, the switch would have to on and therefore closed.
A hot light switch could be caused by an overloaded circuit, loose connections, or a faulty switch. It is important to address this issue promptly to prevent potential fire hazards.
To properly wire a switch in your electrical circuit, first turn off the power to the circuit. Connect the hot wire to one terminal of the switch and the load wire to the other terminal. Make sure to ground the switch if necessary. Secure the connections with wire nuts or screws. Test the switch to ensure it is working correctly before turning the power back on.
