The OR Gate is one of many Logic gates in RedPower 2. The OR Gate has 3 inputs and 1 output. It will output power if it receives power from at least one of its input sides. Similar gates are the XOR Gate, the NOR Gate and the XNOR Gate.
As long as the OR Gate receives at least one input signal then it will give an output signal which, in this case, activates the lamp.

Uses[]
An OR Gate is used for circuits where multiple power sources can power the same thing, such as 3 buttons placed
The OR Gate (in the middle of the picture) takes an input from any of the three levers and then turns on the lamp, as shown in the picture. It doesn't matter if only one or even all of the levers are set to ON, as long as the OR Gate receives input from any of its three input sides it will produce an on signal through its output side.
around a house, that cause a piston to seal the entrance or open a door when pressed. When using buttons or pressure plates however, an equal solution is an Alloy Wire instead. The main difference when using an OR Gate is that multiple signals will only connect to the Output and don't affect any other outcome. This might be useful when more than one gate or cell is connected in the same circuit.

0's represent an inactive signal. 1's represent an active signal.
Note that the outcome is equally to the Output of the OR Gate.
