Does each switch have its own power source?
Not all switch have there own power source, some of the switches are connected with two or more power sources so it is best to have additional switches to avoid a blowout.
What are the different types of low voltage transfer switches available?
There are a few different types of low voltage transfer switches available, including manual transfer switches, automatic transfer switches (ATS), and generator transfer switches. Manual transfer switches require the user to manually switch between power sources, while ATSs can automatically detect and switch to an alternate power source. Generator transfer switches are specifically designed for use with generators and will automatically detect when a generator is running and switch the load to that source of power.
When are series circuits useful-?
when loads act as switches
Hard wired smoke detector versus battery operated smoke detector?
Hard wired detectors are generally better. Some have back up power sources should the city power go out. It depends on how much you want to spend. Hard wired detectors are more expensive to install and are generally built better.

What do you do when the switch and fan for air conditioner does not go on?
Check all possible power sources to the unit, Circuit breaker ,local on/off switches, emergency on/off switches if present, cabinet cover interlock switches on the indoor unit and lastly the fuses in the local disconnect switch near the condenser. If everything is closed and you have power to both units indoors and out and still have nothing, it`s time to call somebody.
If you have a light in your kitchen operated by two different switches is it right that you should still get a power reading when the switches are off?
Yes, because the light is using 3-way switches. There is always "power" travelling between the switches.
How do automatic transfer switches work?
ATS's constantly monitor the primary and secondary sources of power. When the primary source of power goes out, and the secondary is available, the unit automatically switches to the secondary power source. Some ATS's switch back to primary using the same logic, and some have to be manually switched back to primary. There are 'smart' switches that wait until the primary power source is available for a certain length of time (i.e. 2 minutes) until switching back, to avoid connecting to an unstable or intermittent utility source.

What uses does a data transfer switch have?
A data transfer switch can change power sources during a power outage and avoid a shutdown to a critical data center. Data transfer switches can monitor voltage capacity and direct it to circuits that need it for cooling or heating purposes.

What Is Automatic Transformer SwitchATS?
A transfer switch, in general, switches load between two sources. An automatic transfer switch or ATS is usually installed where a generator is located to allow the generator to give power while electricity is out.
