Abstract

A space bar construction is provided for low profile keyboards which will accommodate, with the same construction, from a 1 to 3 space bar up to a 1 to 9 space bar. The arrangement provides a leveling system for the space bar to maintain exactly equal the depressed distances of the space bar at each end thereof through the utilization of a torsion spring for the leveling wire. The torsion spring imparts a constant loading in the leveling wire, and consequently the key top to avoid any noisy 'play' between the parts. The unit is assembled complete as a self-contained module for later insertion into a low profile keyboard.
