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.

Pole refers to the number of circuits controlled by the switch. 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 correlates to the following in the relay. Dual circuit functions can be controlled with a single coil signal.

Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Double pole double throw relays supply two single double through relays spdt in one relay package. 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. 73 6 87 relay get it as soon as thu oct 1.

This combination provides tremendous design flexibility. 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. Place the relay s rated coil voltage on these terminals. 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.
