Double Pole Double Throw Relay Schematic

Double pole double throw dpdt relay contains two coil terminals two separate common terminals c1 c2 and two normally open n o1 n o2 two normally close n c1 n c2 terminals this relay makes two different connection and control with one control signal to the coil.

Double pole double throw relay schematic. The other two terminals are often referred to as a and b. Basically a double pole double throw relay is a electrometric relay which two common points 2 normally close and 2 normally open points. In this article we go over how to connect a double pole double throw dpdt relay in a circuit. An application for this switch is for reversing a direct current dc electrical motor.

It has 2 terminals and 4 connectors and you can look at the dpdt relay as the equivalent of 2 single pole double throw spdt relays. How to connect a dpdt relay in a circuit. And how we use the double pole double throw relay in circuit. What do spst spdt dpst and dpdt mean.

The dpdt relay double pole double throw is quite interesting and can be used in various scenarious including for changing the direction of a motor as you can see in the picture below. This post is about the double pole double throw relay schematic diagram. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions.

In order to know how to connect a dpdt relay you must know what each pin terminal represents and how the relay works. A double throw switch connects an input terminal to one of two output terminals. One of the terminals is called the common terminal. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.

Dpdt relay wiring diagram this is the diagram below to learn all the pin terminals of a double pole double throw dpdt relay. The 2 coil terminals is where the voltage is placed in order to energize the coil. Thus a double pole switch has three terminals. Pole refers to the number of circuits controlled by the switch.

Sp switches control only one electrical circuit. The dpdt relay is mostly used for controlling switching on off changeover switch forward reverse dc motor forward reverse single. The dpdt relay double pole double throw is quite interesting and can be used in various scenarious including for changing the direction of a motor as you can see in the picture below. In this post you will complete learn about the working of double pole double throw relay also known with name of the dpdt relay.

When the switch is in one position the common terminal is connected to the a terminal so current flows from the common terminal to the a terminal but no.
