ABSTRACT:
A key extender includes an elongated member, e.g., a deformable metal rod having a first end portion secured to a contact member, e.g., a circular disc having a contact area greater than the available touch plate surface area of the key. An opposite second end portion of the elongated member is secured to an attachment member, e.g., a binder clip. Mounting an extender on each of the keys of a device and shaping the metal rod to position the discs adjacent to and spaced from one another allows a disabled person to play a musical instrument or perform a similar function.
