 Several devices, such as [[floodgate]]s and [[bridge]]s, have a delayed response to all incoming signals, and will not respond to subsequent signals until the first has taken effect.  For instance, if you pull a lever attached to a floodgate on then off in rapid succession, the floodgate will only respond to the first signal, independent of the position the lever rests in eventually.
-In the unusual case that a device receives both an on and an off trigger in the exact same tick, the device will change states-- an open device will close, and a closed device will open.

 A lever can be linked to any number of objects, and each object can have any number of levers controlling it.
-There is no way to de-link an object without disassembling either object or lever {{verify}}. When using a lever for a single-use purpose (cages or supports), the mechanism in the lever will remain in the lever, but the object and its mechanism will deconstruct. In this manner, a single lever might accumulate many mechanisms. Deconstructing the lever will free all these mechanisms and allow their reuse - keep your permanent and one-time linkages to separate levers.

 In contrast with [[pressure plate]]s, build order does not affect the timing of levers whatsoever.  In any given tick, any levers will send their signals before any furniture receives those signals, so it as if levers are always considered to be built after the furniture they link to.  In rare cases, it is possible for the order of arrival of the dwarf pulling the lever to affect the precise timing of lever-linked devices, as when using a hatch to drop a dwarf-- if the falling dwarf arrived later than the lever pulling dwarf, the dropping dwarf will take an extra tick to fall.

 - hatches, floor bars and floor grates can be placed over a channelled-out tile creating a gap in a passage. When closed (switched "off"), those structures now provide a path across the gap, but block passage when switched "on" and opening. Hatches, like doors, react immediately to signals, which makes them particularly useful for this purpose.
-So, to "switch" between paths with a single lever, you would connect functionally different devices to it, e.g. a door in one passage and a raising bridge in another. Whenever the lever is switched now, it will send the necessary signals to open one path and at the same time close the other.
