Abstract
A keyboard for large scale inexpensive production comprises a housing having a front frame and a base part which are connectable with one another by latch elements to support a printed circuit board in a floating manner. The printed circuit board carries the keys of the keyboard. The printed circuit board is assembled to the front frame with relatively great accuracy via several aligning elements.
