Conical Keyboard Spring
A conical keyboard spring is utilized to provide an additional level of tactile
force without requiring a change in the profile height of the keyboard.
Depression of keybutton 11 effects the downward motion of the key module
13 relative to housing 15. Compression spring 17 provides a resistive force to
this downward motion. Once washer 19 bottoms out on the surface 21 of
housing 15, the conical spring 23 starts to collapse, providing an additional force
which may be felt by the operator. When fully compressed, the coils of the
conical spring 23 fit inside each other so that the compressed height is limited
only by the wire diameter of the conical spring.
