The Double Pole Single Throw DPST relay is the equivalent of 2 SPST switches (NO Normally Open and NC Normaly Closed) and can be used to switch 2 different loads. As you can see in the schematics ...

The addition of an extra contact to an SPST switch lets it turn off one circuit and turn on another. This makes it a single-pole double-throw (SPDT) switch. Double-throw switches can make ...

In its most basic form, a transfer switch for a 120/240V single-phase service is simply a double-pole, double-throw switch of proper ampere rating with a middle off position (Fig. 1). By design, it is ...

In this second application we can use the DPDT switch to choose between 2 different load and have a visual indication of what load is connected. In our case (diagram 1) when there is no voltage ...
