Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw. Below is an example of a circuit which utilizes a double pole double throw switch.
Dpdt Relay
Dpdt switch circuit diagram. A wiring diagram is a streamlined conventional photographic depiction of an electrical circuit. Wire a dpdt rocker switch for reversing polarity. Therefore it can control 4 different circuits or devices with 2 switches. An spdt switch has three terminals. The jameco electronics gts164blk 22841 subminiature switch is similar to the one in the example photos. The jameco electronics swm127 567761 has screws and allows much higher current.
With the circuit above you can see that we can flip between 4 different circuits with 2 switches. A dpdt circuit symbol and a 6 terminal dpdt rocker switch. You can see above how a double pole double throw switch can allow a circuit to be in 1 of 2 modes. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. An example circuit of a dpdt toggle switch is shown below. Xpyt switches with more than two poles or throws are not too common but theyre out there in all their oddly shaped difficult to connect to glory.
A double pole double throw dpdt center off toggle switch. Double pole double throw toggle has 2 input terminals and 4 output terminals. A dpst switch has four terminals. Fig 12 dpdt terminal diagram. Collection of 6 pin dpdt switch wiring diagram. A double pole double throw switch is used for this purpose but you have to wire it up correctly.
Sp switches control only one electrical circuit. Here pole indicates individual input circuit and throw indicates the output circuit. One for the input and two for the a and b outputs. 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. Pole refers to the number of circuits controlled by the switch. Look at picture 11 and 12 it consists of two common input terminals c e and both mechanically tied together to operate in the.
Switch is sometimes called an ab switch because it lets you choose between two circuits called a and b. A dpst switch turns two circuits on or off. When you need to control a dc motor such as a dc linear actuator you usually need to be able to swap the polarity on the wires going to the motor. Nov 4 attachment i have a 7 pin on off on rocker switch that i am trying to wire up i have a diagram that i have attached that came with it and awaterwich 7 pin momentary winch in out rocker toggle switch waterproof dc 20a 12v10a 24v black shellon off on dpdt illuminated rocker switch for auto truck boat marine off road winch. What do spst spdt dpst and dpdt mean. Two inputs and two outputs.
These are sometimes labeled as on off on in catalogs. A dpdt switch has 2 input switches which can each connect to one of 2 terminals. Dpst double pole single throw.
