Single Pole Double Throw Relay

The 2 coil terminals is where the voltage is placed in order to energize the coil.

Single pole double throw relay.

These are the terminals where you apply voltage to in order to give power to the. 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. 4 9 out of 5 stars 34. The number of throws indicates how many different output connections each switch pole can connect its input.

One can be normally closed and the other one is opened or it can be normally open and the other one closed.
