Nikola Tesla was the brilliant physicist who developed logic circuits called gates or switches in 1903. Tesla was a Serbian American inventor.

switches
Energy sources are not always present in circuits as some circuits rely on energy harvested from the environment.
They can, but not required.
when loads act as switches
Dual pole switches offer the advantage of controlling two separate circuits with a single switch. This can provide increased safety by allowing both circuits to be disconnected simultaneously, reducing the risk of electrical hazards. Additionally, dual pole switches can help prevent overloading of circuits by distributing the electrical load across two separate paths.
Double throw double pole switches have two separate circuits that can be controlled by a single switch. This allows for more flexibility in how the circuits are connected or disconnected. When the switch is flipped, it can change the connection of both circuits simultaneously, making it useful for applications where multiple connections need to be switched at the same time.
household circuit comprises of main swith,circuit breakers,wires and control switches.
An SPST switch can break the connection or hold the connection depending on which switch your using.
mostly high speed switches in digital logic circuits
The CPU is housed on a silicon chip that contains millions of switches and circuits. It has millions of Transistors
The output of an AND gate is set only when all of its inputs are set, and when switches are wired together in series, current can flow only when all of the switches are on.
