Simply think. If two switches are connected in parallel in a circuit then the circuit will be active when at least one of the switch is on. So, for one of the switches being on, the circuit will be on.

See the question where it is said to IMAGINE the OR gate as a parallel switch, not to use it as PARALLEL SWITCH.

For addition. You can also imagine a AND gate as switches connected in series.

I don't know exactly but let me explain what I know. We hear that whenever we arrange devices in series if one damages then we can't work with other. If we arrange devices in parallel if one damages also we can work with others. By that see truth table of OR gate below.

0 0 - 0
0 1 - 1
1 0 - 1
1 1 - 1

Here if any variable is 0 and with other variable 1 it works. So by that we may say in OR gate switches are connected in parallel.
