A switch is said to be open when there is no current flow between two terminals and is closed when the current flows from one terminal to the other.
Flat plate grid plates and switches. What is a double pole switch. Well single pole breakers and double pole breakers differ in the voltage and amperage they provide as well as how they are wired. This terminology applies to toggle switches rocker switches and push button switches. Its also because the wires feeding electricity to the switch are larger and this is due to the fact that double pole switches are usually used to control 240 volt circuits.
