Abstract

A key assembly, for a keyboard, includes stabilising arms attached to a shaft of the assembly for correcting any binding caused by tilting of the shaft during keyboard operation.
Also an arrangement for supporting a long narrow top member for a keyboard includes a linking rod held by clips, which, over the central part of the rod, are provided by spaced-­ apart parts of a generally U-shaped member. The spaced-apart parts of the generally U-shaped member would belong to a base member with which the top member is associated.
