The Stacking Latch is a redstone circuit added by Project Red as version 4.5.9. It is a logic gate that acts as a switch with lock function (see Usage).

Usage


The Stacking Latch has one input side, two input/output sides and one output side (shown in the picture) for red alloy cables, redstone, an adjacent circuit, machine, lamp or anything that can be controlled with redstone signals.

Using the screwdriver from Project Red, the orientation of the gate can be changed freely in all four directions.

If a redstone signal receives the gate on the lower input side, then nothing happens. If a redstone signal receives on of the side input/output, then the other input/output side is activated.

The gate allows only the transmission of a redstone signal from the lower side to the upper side, when a redstone signal receives at least one of the side input/outputs. In this position are two interactions are possible:


 * 1) If the lower input is disabled, then the upper output is switched off.
 * 2) If both input/outputs on the side are disabled, then the upper output is locked. This means that, when the lower input is turned off, the upper output remains active. The output is only switched off again when at least one of the two input/outputs on the side receives a new redstone signal.
