Key panel for typing and computer technology

The invention relates to key panel solutions in which the individual key panel devices are permanently arranged on the switching plate. For this purpose, the basic bodies of the key panel devices with the preassembled plungers are mounted directly, either individually or integrated, on the switching plate provided with fixed contacts. If the optional construction of a key switch is effected, the moving switching member with the associated spring system is placed into the plunger in such a manner that the moving switching contact protrudes through the penetration located at the bottom of the plunger. Finally, the key knob can be locked on. In the service case, this can ensure the accessibility of the contact point without problems. The optional assembly of supplementary assemblies in key panel solutions in the form of parallel arrangements of 2, 3 and 8 key knobs, display and cover modules in 1/2 spacing can be effected on the centering areas, lower limit and locking devices formed on the basic body. These supplementary parts allow all required key panel solutions to be constructed with the aid of the fixed basic bodies.
