What do SPST, SPDT, DPST, and DPDT mean? SP and DP refer to single pole and double pole, ST and DT refer to single throw and double throw. Pole refers to the number of circuits controlled by the switch: SP switches control only one electrical circuit. DP switches control two independent circuits (and act like two identical switches that are mechanically linked).

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. 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 .

Assortment of magnetic door contact wiring diagram. A wiring diagram is a streamlined traditional pictorial depiction of an electric circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the tools.

How to Connect a DPDT Relay in a Circuit. In this article, we go over how to connect a Double Pole Double Throw (DPDT) relay in a circuit. In order to know how to connect a DPDT relay, you must know what each pin terminal represents and how the relay works. Terminal Pins. A Double Pole Double Throw Relay comes with 8 terminal points.

Switch Contacts (pole, throw etc.) Standard Switches (SPST, DPDT etc.) Special Switches (multiway, tilt, reed etc.). Also see: Relays | Series & Parallel Selecting a Switch. Features to consider when selecting a switch: Type of contacts such as DPDT.; Ratings for voltage and current.; Method of operation toggle, slide etc.; The following terms are used to identify different types of standard ...

Wiring magnetic door contacts Magnetic door contacts are wired in a similar manner as PIR’s, with one exception, they do not require any power. • The correct wire to use for this type of connection will be a 0.2 mm Ripcord. • Start by connecting the first wire of the ripcord to the right hand side connector of the magnetic contact. •

Below is an example of a circuit which utilizes a double pole double throw switch. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes. When the DPDT switch is switched one way (flipped upward in the diagram), the lamp and buzzer are both on, while the LED and speaker are off.

Wire the inputs and the auxiliary contacts. Use a screwdriver to loosen the holding screws in the contact blocks for the wires. Insert the wires only so far that no insulation is pushed into the contact area of the block. Make sure that no stray strands are jutting out from the contact block. Tighten the screws on the contact blocks.
