A power switch gates a power or ground rail with an enable. It is used to turn-off power to gates (e.g. a block) for power savings. Typically power gates are inserted in P&R.
There is a comprehesive tutorial here:

Power switches are now very common so I imagine there are many other tutorials online. Google search "low power switch".
