First of all note that if the switch was in parallel with an appliance, closing the switch would cause a short-circuit between line and neutral.
Second, the purpose of the switch is to interrupt the line to the appliance, thus it needs to be in series.

In order to complete or break the flow of electricity to the bulb/appliance.
See the great series of books on electricity at the link below. Look at Volume I, DC.

it is so because in parallel the voltage remains same which is a major requirement for any appliance to run perfectly, so if the appliance takes more current it will not affect the working of other appliances that much as it wuold have done if connected in series where voltage change wouyld have occured.
