What are the different types of toggle switches?

There are two basic types: maintained contact and momentary toggle switches. A maintained switch changes its position when actuated and will remain in that position until actuated again, such as an ON/OFF function. A momentary toggle switch is actuated only when someone is operating the switch.

Is common wire negative or positive?

So the negative connection of the supply in this case would be called "common" or 0V. 0V because all voltages within the circuit are measured from that common point, which also happens to be the supply's negative pole.

What happens if you reverse hot and neutral wires?

One common issue with electrical outlets is reverse polarity, also known as "hot-neutral reversed." In this condition, the outlet has been wired incorrectly, altering the flow of electricity. While the outlet will still be able to provide power to your electrical items, it is also present a greater shock hazard.
