Double Pole Double Throw Relay Schematic

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.

Double pole double throw relay schematic.

In order to know how to connect a dpdt relay you must know what each pin terminal represents and how the relay works. This is the diagram below to learn all the pin terminals of a double pole double throw dpdt relay. The 1 terminal is common which is normally close with 2 and normally open with 3. Place the relay s rated coil voltage on these terminals.

In this article we go over how to connect a double pole double throw dpdt relay in a circuit. A positive and negative voltage can be placed on either end. How to connect a dpdt relay in a circuit. A double pole double throw relay comes with 8 terminal points.

Fig 1 2 dpdt terminal diagram. Dpdt relay double pole double throw. 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. A double throw switch connects an input terminal to one of two output terminals.

Double pole double throw toggle has 2 input terminals and 4 output terminals. Look at picture 1 1 and 1 2 it consists of two common input terminals c e and both mechanically tied together to operate in the. Also a 8 pin glass finder types relay with also a dpdt relay with diagram. The following are industry accepted relay schematics and forms that gigavac uses for most of its relays.

The motor s two power leads are reversed at one of the switches screw terminals. An application for this switch is for reversing a direct current dc electrical motor. I shown a power relay with schematic diagram. In the above double pole double throw relay schematic diagram.

The 2 coil terminals is where the voltage is placed in order to energize the coil. A double pole double throw dpdt switch is a three selection electrical device in which there is one off and two on positions. Single pole single throw normally open spst no form a single pole single throw normally closed spst nc form b single pole double throw spdt form c double pole double throw dpst no 2 form c. Thus a double pole switch has three terminals.

Here pole indicates individual input circuit and throw indicates the output circuit. 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. One of the terminals is called the common terminal. In the diagram a1 and a2 is coil terminals of electromagnetic relay.
