Double Pole Double Throw Relay

Pole refers to the number of circuits controlled by the switch.

Double pole double throw relay.

Dpdt stands for double pole double throw relay which is an electromagnetic device used to separate two circuits electrically and connect them magnetically. 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. 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.

Sp switches control only one electrical circuit. 73 6 87 relay get it as soon as thu oct 1. 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. This combination provides tremendous design flexibility.

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. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. The terminals are coil coil com com no no nc nc.

Dual circuit functions can be controlled with a single coil signal. 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 relays supply two single double through relays spdt in one relay package. A double pole double throw relay comes with 8 terminal points.
