NO SPST Normally Open Relay

The NO Normally-Open SPST (Single Pole Single Throw) relay has an opened circuit state when no current is applied to its coil so basically it disconnects the power to the load in the inactive state. When current is applied to its coil the generated magnetic field switches the armature and closes the contact so you can say that it turned ON the load (fan, light bulb, etc).
