Single pole double throw switch schematic. It has one common terminal and 2 contacts in 2 different configurations. A double pole switch controls two separate circuits. So basically you can see the spdt relay as a way of switching between 2 circuits.

Below is an example of a circuit which utilizes a double pole single throw switch. When there is. When the switch is connected one way for circuit a and circuit b the lamp and led will both be on.

Some spdt switches have a central off position and are described as on off on after selecting the spdt symbol you can change the switch position up center or download by the action button. It can serve as an on off switch depending on how the circuit is wired. They are commonly denoted 3pst 3pdt 4pdt.

A single pole double throw switch can serve a variety of functions in a circuit. Look at the figure 1 2 the centre dotted line indicates that the dpdt switch is actually two spdt switches in one package. Double throw closes a circuit in the up or down position on on.

The center position is off. A dt switch can also have a center position frequently on off on. A double throw switch can also have a center position such as on off on.

A 5 d2 i controls the switch com 1 a1 i o bidirectional signal to be switched gnd 3 c1 ground pin gnd 4 d1 ground pin inh 2 b1 i enables or disables the switch vcc 8 a2 power pin y2 6 c2 i o bidirectional signal to be switched y1 7 b2 i o bidirectional signal to be switched. The following switch diagrams illustrate the most common types of toggle and rocker switch. In other words it s like two simple switches controlled by a single actuator.
