	Relays have a connection scheme determined by the arrangement of contacts within the relay. Because relays are a type of switch, they are defined in the same way other electromechanical switches are defined.		Relays have a connection scheme determined by the arrangement of contacts within the relay. Because relays are a type of switch, they are defined in the same way other electromechanical switches are defined.

	In switch schemes, the number of poles represents the number of common terminals a switch has, and the number of throws represents the number of switchable terminals that exist for each pole. The relays used in the InterfaceKit 0/0/4 are SPDT relays: single pole, double throw. The internal construction of this type of relay is depicted in the diagram above. Many other types of relays exist: SPST, DPDT, and DPST, to name a few.

Many other types of relays exist: SPST, DPDT, and DPST, to name a few.

	In an SPDT relay, one of the throw terminals is labelled ~~Normally Closed~~ (NC), and the other is labelled ~~Normally Open~~ (NO). As the name indicates, the normally closed terminal is the terminal connected to common when the relay coil is not powered. When the relay coil is energized by the relay control circuit, the electromagnetic field of the coil forces the switch element inside the relay to break its contact with the normally closed terminal and make contact with the normally open terminal. The switch element would then connect the normally open terminal and the common terminal.		In an SPDT relay, one of the throw terminals is labelled ''normally closed'' (NC), and the other is labelled ''normally open'' (NO). As the name indicates, the normally closed terminal is the terminal connected to common when the relay coil is not powered. When the relay coil is energized by the relay control circuit, the electromagnetic field of the coil forces the switch element inside the relay to break its contact with the normally closed terminal and make contact with the normally open terminal. The switch element would then connect the normally open terminal and the common terminal.

	Connect the load (typically a DC Motor) to the COM terminals of the relay. The ~~NormallyOpen~~ (NO) terminals are connected to the power supply (VCC), and the ~~Normally-Closed~~ (NC) terminals are connected to the ground (GND) of the power supply. You can toggle the corresponding output to switch the relays.		Connect the load (typically a DC Motor) to the COM terminals of the relay.

You can toggle the corresponding output to switch the relays.

	Looking at the diagram, when LeftCtrl is enabled and RightCtrl is disabled, the current will flow from the NO terminal of relay K1 through the motor and into the NC terminal of relay K2. This will cause the motor to rotate in one direction.

	===Wetting Current===		===Wetting Current===
			When a relay is in one switch position for a period of time, oxidation of the open contact(s) can occur. Depending upon the internal coating material of the contacts, oxide films of varying density will be displaced upon the surface of open contacts; this film acts as an insulator to current flow. When the relay is switched, a certain amount of current flowing through the contacts, known as the wetting current, is required to remove the film of oxides and ensure proper conduction. Because of this requirement, these relays are not reliable for signal switching. Check the specification table for your relay board to find out the Minimum Load Current or ''Wetting Current''.
