Buttons, originally cut content in The Binding of Isaac: Rebirth, have become a full-fledged feature of The Binding of Isaac: Afterbirth.
Silver Buttons appear in trap rooms, which have hazards in them which disarm upon pressing all of the silver buttons in the room. Hazards include:
Once pressed, all the hazards will be disarmed - spikes will retract, Red Poop will transform into regular Poop, Red Fire Places will turn into regular Fire Places, Purple Fire Places will turn into Blue Fire Places, and Pitfalls will close.
Unlike Reward Plates, all Silver Buttons in the room have to be pressed to clear the room even if all enemies are slain.
Bug! In trap rooms with retracting spikes, pressing the silver button within five frames of the spikes deploying will cause them to appear to fail to retract, but this is only a visual bug, and they will not deal damage. This can be fixed by leaving the room and re-entering.
Reward Plates (Spawn Buttons)[edit | edit source]
Reward Plates can appear in a variety of rooms, including Secret Rooms, Curse Rooms, and Shops in Greed mode. When pressed, they may spawn helpful pickups or harmful enemies.
This list is currently incomplete.
There is a 50-50 chance to spawn a reward or a monster.

The Chest
- A Reward Plate may spawn a trapdoor even in The Chest. If that happens and Isaac enters them, the floor is restarted as with Forget Me Now or 5-pip Dice Room.
- If it spawns enemies, the doors to the room will not close, allowing Isaac to avoid fighting them.
- It may be worth fighting Sins as they still drop items on death.
This was changed in Booster Pack #5. If it spawns enemies then the doors will close. The enemies will remain in the room even after escaping via teleportation or bombing out.
- When enemies are spawned, they appear only at walls with doors (barring an I AM ERROR room where the locations are random). This may help locating Secret Rooms as their secret doors also count.
- Different enemies may spawn from the buttons depending on the floor, with difficult enemies such as Bosses being spawned on later floors.
- Donation Machines spawned in Greed mode will be regular Donation Machines and not Greed Donation Machines.
