Keyboards having space bars often require stronger return force in the space bar mechanism because of the additional weight of the longer key button assembly. The additional force is usually provided by separate return springs or of a higher force return spring in the space bar key module. Some inertia balance mechanisms are also utilized and they work well, but are more complicated to assemble and require considerable space.
