The DPDT relay is an electronic device that controls four circuits. It has two inputs and four outputs, which allows it to control the direction of a motor. It is often used to control electronic devices that have complex circuitry. Because it is so versatile, it can be used in a wide variety of applications.

The DPDT relay is also known as a double-pole, double-throw relay, or simply a DPDT relay. DPDT relays come in many shapes, sizes, and styles, and can be used to control electrical devices. One type of DPDT relay has two normally open contacts and one normally closed contact. These types of relays have low contact resistance, allowing them to carry high currents while drawing little current from the power supply.

A DPDT relay has two coil terminals, one common terminal, and two normally open/closed terminals. The two coils are controlled with one control signal. When the DC bias is off, the DPDT relay remains in an idle state. When DC bias is applied, the common terminal levers are attracted and create a connection between the N/O and N/C terminals. This causes the N/C terminals to open.

The DPDT relay is more versatile than the SPDT. While SPDT relays can only switch an output circuit on and off, a DPDT relay can turn on multiple appliances simultaneously.
