Each input has 1 corresponding output. This makes the the double pole double throw switch a very versatile switch.

What is a dpdt switch. Used to switch 120v to two different appliances that could not be run simultaneously. On the other hand dpdt is basically two spdts together on the same switch. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs. A double pole single throw dpst switch is a switch that has 2 inputs and 2 outputs. Each of the terminals of a double pole single switch can either be in the on position closed or in the off position open. St switches close a circuit at only one position.
A dpdt switch usually has two on on or three on off on positions. Adding another pole to the spdt creates a double pole double throw dpdt switch. Mouser offers inventory pricing datasheets for dpdt on on pushbutton switches. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs. Throw refers to the extreme position of the actuator. There are many situations on a model railway layout where a dpdt switch can be useful.
Do not confuse pole with terminal. Each of the terminals of a double pole double switch can either be in 1 of 2 positions. The other position of the handle is off. Dpdts should have six terminals. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Dpdt on on pushbutton switches are available at mouser electronics.
It is a dual on on kind of switch derived from the characteristics of spdt. A special switch that you just cant find at your local hardware store. Each input has 2 corresponding outputs that it can connect to. They can be used as onoff or onon switches. A dpdt double pole double throw switch allows two completely separate circuits to be controlled by just one switch. Each of the terminals of a double pole double switch can either be in 1 of 2 positions.
Basically two spdt switches which can control two separate circuits but are always switched together by a single actuator. With 2 inputs it can connect to 4 different outputs. Each input has 2 corresponding outputs that it can connect to. This makes the the double pole double switch a very versatile switch. The dpst switch for example has four terminals but it is a dp not a 4p switch. The pair of spdt switches operates together with four circuits with two independent circuit systems.
