NOTE: Redstone lighting will not prevent mobs from spawning.
Switches will power a redstone circuit, an adjacent device, or an adjacent block. The length of time varies, based on the device used. Although switches can be used to power things, not all of them require redstone when crafting.
A pressure plate is a switch that is activated by a player, mob, or item laying on it. However, only wooden pressure plates will be activated with items, not stone ones. Any item when dropped will trigger the pressure plate, and it will power any wire or blocks near it. They can be used to make traps, as stone pressure plates are well hidden on stone and wooden pressure plates are well hidden on wooden planks. Use of these in combination with a dispenser or two is ideal. The can also be used as a way to auto-open and close doors.
A lever is a way to power a current. Levers can be placed on walls and floors. Once turned on, they power a current into their adjacent block until turned off. Levers are made from sticks and stone.
A button is another way to power a current. Buttons can only be placed on walls, and only power the adjacent block for a short time, before switching off again. They are best used for opening doors, and powering a dispenser so that it dispenses one thing, then another if pressed again. A button is made from one smooth stone or one Wooden Plank.
A detector rail simply detects a minecart passing over it, and sends a current to any redstone placed next to it. The rail powers redstone as long as a cart is on top of it.
