A double pole single throw dpst switch is a switch that has 2 inputs and 2 outputs. Each input has 2 corresponding outputs that it can connect to.

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