Dpdt Diagram. Sp switches control only one electrical circuit. It shows the elements of the circuit as streamlined forms and the power as well as signal links in between the gadgets.
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. The input supply always is given to the common terminal c and e only. 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.
It shows the elements of the circuit as streamlined forms and the power as well as signal links in between the gadgets.
What do spst spdt dpst and dpdt mean. Dp switches control two independent circuits and act like two identical switches that are mechanically linked. Below is an example of a circuit which utilizes a double pole double throw switch. Sp and dp refer to single pole and double pole st and dt refer to single throw and double throw.
