Yes a circuit will work without a switch but the only problem will be is that electricity will be wasted and there will be no device to stop the flow of current
When a switch is closed the path through the circuit is continuous.
If someone only connect one of the wires to the bulb holder, the circuit will be open and the lamp will not light. This is the same principal that a switch in the circuit does. It opens and closes the circuit.
You don't experience a shock in an open circuit. The only time that you can get a shock from an open circuit is when you act as a switch and close the circuit or you ground the circuit hot side to ground with your body. Current has to flow to give you a shock.
You never switch a neutral wire, only hots. hooking both hot and neutral to the same switch will result in a short when the swith is turned on.

Because a switch is a 'permanent' action. A relay only completes the circuit while there is power. If there is a fault in the circuit, a switch will still allow power through, whereas a relay will break the circuit.

a switch is rarely used in electrical circuits
Electricity flows in a complete circuit
A fuse can break the current flowing in a circuit only once whilst a switch can break the current flowing in a circuit many times. In other words a switch can switch the current on and off - and then on again and off again - indefinitely but a fuse can only switch off the current once.
A switch basically represents a gap in the electric circuit. Electric current can pass through a circuit only if it is complete. An incomplete circuit can never pass a current through it. When the switch is in the 'off' position, the circuit has a break (gap) in it. When you put the switch in 'on' position, the circuit wire join and the circuit gets completed.
A tact switch is type of switch that is only on when the button is pressed. As soon as you release the button, the circuit is broken. Think of the keys on a keyboard.
Electricity only works when it can flow all the way around a loop called a circuit. Turning off a switch breaks the circuit, stopping the flow and turning electrical things off. Turning a switch on joins the circuit and makes them work again.
a neutral safety switch only allows the car to start when the gearshift is in park or neutral. It is normally located on the top of the transmission. the switch closes the circuit so power can be sent to the starter circuit.
From the standpoint of basic functionality, you can put the switch anywhere. In a series circuit, there is only one path for current flow. If you open the switch, you interrupt that pathway and turn the circuit "off."There may be practical reasons to put the switch in one place or another, however. Sometimes it's put in a particular place in the circuit for manufacturing reasons. In other circuits, safety may dictate that you put the switch in a particular place: in a ground-referenced circuit for example, you may want to put the switch so that one side is at the ground point.
Only because the circuit that its embeded in is designed that way. Remember, a transistor is basicly an amplifier ... only if you design everything to go to the extreams will it act as a switch.
