Double Pole Double Throw Relay

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.

Double pole double throw relay.

The terminals are coil coil com com no no nc nc. The 2 coil terminals is where the voltage is placed in order to energize the coil. 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. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.

Dpdt stands for double pole double throw relay which is an electromagnetic device used to separate two circuits electrically and connect them magnetically. 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. 73 6 87 relay get it as soon as thu oct 1.

Place the relay s rated coil voltage on these terminals. They are often used to interface an electronic circuit which works at a low voltage to an electrical circuit which works at a high voltage.

Dpdt relay wiring diagram this is the diagram below to learn all the pin terminals of a double pole double throw dpdt relay. This combination provides tremendous design flexibility. A double pole double throw relay comes with 8 terminal points. Pole refers to the number of circuits controlled by the switch.

This correlates to the following in the relay. Double pole double throw relays supply two single double through relays spdt in one relay package. Dp switches control two independent circuits and act like two identical switches that are mechanically linked.
