ABSTRACT:
A multiple-key key assembly includes an integrated key top and key base unit with a built-in stabilizer. The key top includes a key plunger for mating with a key plunger guide provided in the key seat of a keyboard to support the key assembly on the keyboard and for making key stroke contacts with depression of the key top. The stabilizer includes a swing rod connected in a movable fashion between the key top and the key base. When eccentric actuation occurs from the top of the key top, the eccentric force is deflected by the swing rod and uniform force transmission is achieved to provide smooth operation of the integrated key. A support plunger provided in the key top is guided by a support plunger guide provided in the key base for added stability. The integrated structure with the built-in stabilizer allows the integrated key assembly to be adapted to a wide range of multiple-key applications, including double and quad keys. The integrated key assembly can be easily assembled to or disassembled from the keyboard by connecting or disconnecting the key plunger to the key plunger guide without the need for special tools.
