Pressure Plates were introduced in the third Seecret Friday update. If connected by wire to an object (or placed adjacent to a block that requires electricity), they will provide power to that object or block when stepped on by either a player or a mob (as well as other items; see below), and will stop when stepped off. Pressure plates are one of the three types of switches currently in the game.
Stone and wooden plates can be recovered with a pickaxe. Both can also be recovered by destroying the block they are on.
Crafting
There are currently only two types of pressure plates: wood and stone. Wooden pressure plates are made from 3 wooden blocks in a horizontal line, and stone pressure plates are made with Stone (not Cobblestone) in the same fashion; see crafting.

Triggering
Pressure plates may be triggered in the following ways:
- A player or mob standing on a plate.
- A dropped item (the kind you can pick up by walking onto) on a wooden plate (stone plates are not affected). Sand or gravel falling onto a pressure plate will convert into a dropped block, but it will not necessarily land on the pressure plate unless there are walls around it.
- Minecarts:
- Any type of minecart will trigger a wooden plate.
- A minecart with a mob or player riding it will trigger a stone plate (however, storage minecarts and powered minecarts do not trigger stone plates).
- Pressure plates do not act as minecart tracks, so the cart will stop on the plate unless it has very high momentum.
- A minecart on a curved track may trigger a pressure plate adjacent to the track (think about the cart's corners sticking out). However, this is not reliable.
- An arrow fired into a wooden pressure plate. However, it will only trigger if there is a flaming block directly adjacent or directly under it. The fire increases the speed with which the pressure plate updates its state. A plate enabled with this method remains turned on until the arrow is recollected or despawns (which takes exactly one minute as of v1.2.4_01), whether or not there is still fire present.
- There is a mode to allow pressure plates to be activated only by humans, and not mobs. However, no block in the game currently uses this feature (except some mods).
