The NOT Gate is a redstone circuit added by Project Red. It is a logic gate for complex redstone circuits. It emits a redstone signal, if no signal reaches the gate (see Usage). The difference to the NOR Gate is the number of inputs and outputs.

The circuit would be possible with Vanilla redstone mechanics, but this block reduces the size of the circuit to 1 block. This makes complex circuits clearer and easier to control. In electronics, this gate enables the physical execution of the Boolean function "NOT" (logical negation / inverter).



A NOT Gate from "Project Red" with input and output sides indicated by WAILA

For an easier usage, NEI and WAILA could be installed, which show the input and output on the NOT gate.

The NOT Gate has one input side and three output sides for red alloy cables, redstone, an adjacent circuit, machine, lamp or anything that can be controlled with redstone signals.

If there is no redstone signal on the input side, then a redstone signal is emitted on all three output sides. If a signal reaches the input, then no signal is transmitted through the output sides. Due to this property, the gate is called aninverter ("a signal causes no signal," respectively "no signal causes a signal").

Using the screwdriver from Project Red, the orientation of the gate can be changed freely in all four directions. Furthermore, using the screwdriver in crouching, the output sides can be turned off and on again in various combinations.
