ABSTRACT:
A keyboard assembly includes a U-shaped carrier member and a plurality of key members connected thereon by resiliently yieldable legs having detent portions which engage cooperating recesses provided in the bottom wall of the U-shaped carrier member with snap action. Each key member has an upper and a lower housing port which are snap-fastened to each other, and an actuating shaft axially movable to energize an electrical component mounted below the carrier member. A locking member is also provided to lock the shaft in a down actuating position.
