Buffered Terminal Key Fusing

This push-button device is fused against jamming. There are two halves 10 and 11 of the shell for the push button, a base 12, a spindle 13 a wheel 14, a spring 15 and a flexible blade 16.

When assembled, blade 16 fits in grooves 17 and 18 and rides over wheel
14. The latter rides on spindle 13 and spring 15 pushes upwards against such spindle. Pushing the button down compresses spring 15 and forces blade 16 down as shown by arrow 19.

In the event blade 16 becomes jammed, the button can still be pushed without damage due to the fusing arrangement. Opening 20 is fashioned in the enclosure for blade 16 to allow the latter to form a convex protrusion 21 through the opening, absorbing the compression forced when the operating end of blade 16 or wire becomes jammed.
