GFCI's are not used to protect a switch they are used to protect an outlet where something is plugged in.
No, an electrical approved switch is used to break an electrical circuit.
If you get sparking in an electrical switch there is a loose connection or short in the circuit. The switch should be repaired or replaced.
In the electrical trade, this device is known as a circuit breaker.
When you switch off an electrical circuit you tend to create a 'break' in the circuit, preventing the electric current to flow around the circuit, this can be caused by a simple switch or a break in the circuit, e.g a disconnected wire.
If it is a physical switch, this is called a "relay" or a "contactor". If it is a semiconductor device, it is typically a triac, SCR or a thyristor.
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
opens and closes the circuit
No, an electrical approved switch is used to break an electrical circuit.
The definition of a switch is a device that closes and opens an electrical circuit.
it starts a circuit by connecting the circuit and the initials are ptm and its a spdt switch
Electrical discrimination is to do with selecting the correct protection in the fault path of an electrical circuit. To illustrate, if you have a machine at the end of an electircal circuit and that is protected by a 13A fuse lets say, and then you have a 20A circuit breaker protecting that at the consumer unit (fuse board), and then the main switch on the consumer unit is a 10A circuit breaker, then every time the machine uses more than 10A of power the main switch will trip and disconnect everything connected to it, that is where discrimination is not achieved. Basically it is where the circuit protection closest to the macine is smaller and it gets bigger as it goes boack to the source, then discimination is achieved. I hope that helps. If not then it probably need a drawing to help answer.
Not sure what you mean with "lemon circuit", but in an electrical circuit, the switch can be just about anywhere.

For an electrical circuit to keep going, it cannot be interrupted. When the switch is adjusted, the electrical flow is interrupted. Move the switch again and the flow is restored. Without a switch a circuit is no longer considered a complete circuit. Simple fifth grade science.
A switch is used to make or break an electrical circuit.
A switch is used to make or break an electrical circuit.
Electrical currents require a circuit to flow. If the circuit is broken, then the electrical current will not flow. A switch is a prime example of this principle. When a switch is off, the circuit is broken. However, when it is turned, the circuit is completed and allows for the electrical current to flow through the appliance.
