It is interesting to read the "Summary of the Invention" as stated in the Brown
Bros. patent for the leaf spring dual paddle, I quote as follows: "Among the
objects of the invention are the elimination of loose of high resistance
connections because of poor pivot connections, closer contact adjustment
because of absence of lateral or vertical play in the leavers, and reduction in
contact bounce because of damping effect of the hinge construction.
Other objects include a reduction in the number of adjustments to two-contact
spacing and spring tension by elimination of pivot adjustment, and
selectability of paddle spacing.
The unit provides a solid low resistance circuit from the contact points to the
terminal strip, is complete in itself so that none of its parts need be
separately supported on the base. Simple but effective insulation of the
contact points on the levers from the base is effected by supporting the lever
hinges on a single block of insulation. The unit provides a better feel in
operation because of the elimination of adjustable pivots." To sum it up ,
Brown's patent is claiming the elimination of the pivot provides a lower
resistance connection (switch) and a better feel because of less play. It did
not work out quite that way. Too bad it is so stiff. - 73's - Corn - k4own
