There are two types of braille keyboards. The most common type of braille keyboard is the chorded keyboard used on the Perkins brailler and on electronic braille notetakers. These keyboards do not have a separate key for each letter. There is one key for each dot of a braille cell. To type one letter, all of the keys that correspond to the dots in that letter are pressed at the same time. The brailler or notetaker advances to the next letter after the keys are released. A spacebar is located below the main keys.
Occasionally, one may find a computer or typewriter keyboard that has been labeled with braille letters. Most blind people do not use these, as they learn to memorize the keyboard layout and type by touch. Good sighted typists use the same memorization techniques to speed up typing. Typically, labelled QWERTY keyboards are only used by young children, newly blind adults, or people with additional disabilities who have difficulty memorizing the keyboard layout.
Please see attached links for pictures of the braille keyboards on the Perkins brailler (a braille typewriter) and an electronic braille notetaker.
Braille is an alphabet made up of patterns of raised dots that can be read by touch.

A Braille typewriter moves the paper under the platen one letter space after each pressing of the appropriate 'dot'(s). When the paper can move no further, the keys no longer press.

It depends what you mean by 'Braille keyboard'. If you mean a keyboard for use on a computer - most keyboards already come with a raised area on the 'home' keys of 'F' and 'J' so a person can position their hands without looking. If you mean a keyboard to type in Braille - contact your local blind charity - they'll have contacts of companies that manufacture the devices.
