A pressure plate is a non-solid block that can be used to detect players, mobs, items, etc. It has four variants:

Grid Oak Pressure Plate.png Wooden pressure plate: Can detect all entities, giving out a maximum signal strength.
Grid Stone Pressure Plate.png Stone pressure plate: Can only detect players and mobs, giving out a maximum signal strength.
Grid Weighted Pressure Plate (Light).png Light weighted pressure plate: Can detect all entities. The signal strength increases as more entities are added.
Grid Weighted Pressure Plate (Heavy).png Heavy weighted pressure plate: Similar to a light weighted pressure plate but requires much higher quantities to be activated.

Obtaining[edit]

A wooden pressure plate can be mined using any tool, or without a tool, however, axes are the fastest. All other types can only be mined with a pickaxe.

A pressure plate will also be removed and drop itself as an item:

  • if the block beneath it is moved, removed, or destroyed
  • if a piston tries to push it or moves a block into its space

Natural generation[edit]

Pressure plates used as tables in a village library.

One stone pressure plate is generated naturally in each desert temple.

Wooden pressure plates are generated naturally in villages on top of fences as a table.[Java and Legacy Console editions only]

Usage[edit]

A pressure plate can be used to craft detector rails, to smelt items, or can be used as a redstone component.

A pressure plate can be used to detect entities on top of it (players, mobs, items, etc.).

Placement
Pressure plate placement and behavior.
Pressure plates on fences.

To place a pressure plate, use it while aiming at the face of a block adjacent to the destination space.

A pressure plate can be attached to:

A pressure plate cannot be attached to the side or bottom of any block, but attempting to make such an attachment may cause the plate to attach to the top of a block under the destination space. For example, if a fence is on the ground, attempting to attach a plate to the side of the fence will cause the plate to be attached to the top of the ground next to the fence instead.

Activation

A pressure plate activates when an entity is on top of it (specifically, when the entity's collision mask intersects the bottom quarter-block of the pressure plate's space, which may include entities flying close to the ground) and deactivates 5 redstone ticks (0.5 seconds, barring lag) after no entities are on top of it, with a minimum activation time of 10 redstone ticks (1.0 seconds, barring lag).[verify]

A stone pressure plate is activated only by mobs (including players), while a wooden pressure plate or a weighted pressure plate is activated by all entities (including players, mobs, items, arrows, experience orbs, fishing bobs, etc.) besides snowballs.

A minecart traveling on rails will activate a pressure plate next to a diagonal track but not one next to a straight track (stone pressure plates are activated only if the minecart contains a mob or player).

While active, a pressure plate:

For stone and wooden pressure plates, the power level is always 15. For weighted pressure plates, the power level varies depending on the number of entities (see Required Entities for Weighted Pressure Plate Signal Strength Table, right).

The signal strength from a weighted pressure plate does not vary with the type of entity: all entities have the same "weight" (for example, two mobs produce the same strength as two dropped items). An item stack counts as a single entity, no matter how many items are in the stack. When multiple items of the same type fall on a weighted pressure plate, they may initially be separate item entities and the weighted pressure plate will count them separately, but if they then collapse into a single item stack entity the signal strength from the weighted pressure plate may go down.

Water and lava will flow around a pressure plate without affecting it.

A pressure plate is not solid (it is not a barrier to entity movement). A block under a pressure plate can provide a solid barrier underneath it (for mobs to walk across, items to fall on, etc.), but when a pressure plate is placed on a block with a small collision mask, such as a fence or nether brick fence, it is possible for entities to move through the pressure plate while still activating it (walking through it horizontally, or falling through it vertically). Thus, a pressure plate on a fence can be used to detect entities without stopping them (more compactly than a tripwire circuit).

Pressure plates are 0.0625 blocks high (116 of a block) when inactive and 0.03125 blocks high (132 of a block) when active, but because they are not solid they do not affect the position of entities "on top" of them (for example, a player on top of a pressure plate is actually standing on the block beneath it).

Fuel[edit]

Wooden pressure plates can be used as a fuel in furnaces, smelting 1.5 items per pressure plate.

History[edit]

Java Edition Classic
May 21, 2009 Notch shows interest in adding pressure plates.
Java Edition Alpha
v1.0.1 Oak Pressure Plate Revision 1.pngStone Pressure Plate Revision 1.png Added wooden and stone pressure plates.


Their inventory textures were considerably thicker and were centralised.
Java Edition Beta
1.3 Pressure plates only require two wood planks/stone to craft; previous versions required three (this recipe now creates wooden or stone slabs).
1.5 Stone pressure plates are now used to craft detector rails.
1.6 Wooden plates no longer require a pickaxe to be successfully extracted; before they used to. Both types of plates can also be recovered by destroying the block they are on.
Pressure plates may no longer be placed on leaf blocks. Pressure plates placed on leaf blocks prior to this update will drop when stepped on and may be recollected.
1.8 ? Pressure plates are placeable on fences, though they are not functional as pressure plates in this configuration.
Java Edition
1.0.0 Beta 1.9 Prerelease 2 Pressure plates now function when placed on top of fences.
Beta 1.9 Prerelease 5 Oak Pressure Plate.pngStone Pressure Plate.png Updated the textures.
1.3.1 12w21a A stone pressure plate now generates in desert temples.
12w22a Inventory sprites for blocks were flipped from left to right, changing

to

.
12w23a Wooden pressure plates can be activated by arrows.
1.5 13w01a Light Weighted Pressure Plate.pngHeavy Weighted Pressure Plate.png Added weighted pressure plates.


These too had the thick inventory models.
1.7.2 13w36a Rescaled output strength of weighted pressure plates.
Allowed all entities to trigger weighted pressure plates.
1.8 ? Gave pressure plates unique item names.[1]
1.9 15w31a



Made the inventory and item appearances thinner and closer down.
15w43a Non-stone pressure plates are given a different, more high-pitched activation sound, so that they no longer match the sound of stone pressure plates.
15w46a Mobs no longer spawn on pressure plates.
1.13 17w47a The oak pressure plate ID has been changed from wooden_pressure_plate to oak_pressure_plate.
Birch Pressure Plate.pngSpruce Pressure Plate.pngJungle Pressure Plate.pngAcacia Pressure Plate.pngDark Oak Pressure Plate.png Pressure plates now come in all six types of wood.
Renamed to <wood type> pressure plate.
Prior to The Flattening, these blocks' numeral IDs were 70, 72, 147 and 148.
18w20a Renamed "Weighted Pressure Plate (Heavy)" to "Heavy Weighted Pressure Plate", and "Weighted Pressure Plate (Light)" to "Light Weighted Pressure Plate"
Pocket Edition Alpha
0.13.0 build 1 Oak Pressure Plate.pngStone Pressure Plate.pngLight Weighted Pressure Plate.pngHeavy Weighted Pressure Plate.png Added pressure plates and weighted pressure plates. Stone pressure plates are used to craft detector rails.
Bedrock Edition
1.2.14 build 1 Birch Pressure Plate.pngSpruce Pressure Plate.pngJungle Pressure Plate.pngAcacia Pressure Plate.pngDark Oak Pressure Plate.png Pressure plates now come in all six types of wood.
Water now can be placed in the same block as pressure plate.
Legacy Console Edition
TU1 CU1 1.0 Patch 1 Added pressure plates.
TU5 Pressure plates are placeable on fences.
TU14 1.04 Wooden pressure plates can be activated by arrows.
TU19 CU7 1.12 Added weighted pressure plates.
TU69 CU57 1.76 Patch 38 Birch Pressure Plate.pngSpruce Pressure Plate.pngJungle Pressure Plate.pngAcacia Pressure Plate.pngDark Oak Pressure Plate.png Pressure plates now come in all six types of wood.

Pre-1.7.2 requirements[edit]

Before 1.7.2, weighted pressure plates could only be activated by drops, and they required larger quantities.
