DPDT is an electrical switch type. What does DPDT stand for?

• A. Dual pole, Dual Throw
• B. Double Pole, Double Throw
• C. Dual Pole, Double Throw
• D. Double Pole, Dual Throw

Answer: (A)

DPDT stands for Double Pole Double Throw. Here, “pole” means the switch can control two independent circuits, and “double throw” means each of those circuits can connect to one of two outputs. In other words, you have two common contacts that can be routed to two different terminals, giving four possible connection combinations when you flip the switch. That’s why the standard term uses “Double” for both parts. Some people use “dual”, but the conventional terminology in electrical references is Double Pole Double Throw.
