Definitions

  • the present invention relates to push-button switches, and in particular long-stroke switches which can be used in a group, such as a keyboard, or individually as a discrete stand-alone switch.
  • a long-stroke switch is understood by industrial convention to have a travel of 2.28mm (0.090 inch) or more, as opposed to short-stroke and medium- stroke switches, which have a travel of 0.5mm (0.020 inch) or less and between 0.5mm and 1.5mm (0.020 and 0.060 inch), respectively.
  • Short-stroke switches offer only limited perceived movement to the user. That is, it is often difficult for the user to "feel” that the switch has moved.
  • Long-stroke switches provide excellent tactile response and "feel”.
  • the present invention provides a long-stroke push-button switch assembly.
  • the switch assembly comprises a housing supported on a base and depressible key means operatively associated with the housing and arranged for reciprocable travel relative to the housing.
  • Normally-open short-stroke contact means are provided below the base, with the axis of movement of the contact means being parallel to but spaced from the axis of movement of the key means.
  • a lever means is pivotably mounted relative to the housing and operatively associated with the contact means for closing the contact means when the key means is depressed.
  • a spring means interconnects the key means and the lever means.
  • the keytop 12 is arranged for reciprocal travel relative to a housing 22. As best seen in Figures 2 to 4, the keytop 12 is substantially in the shape of an inverted hollow cube open at one end. The keytop 12 thus fits over the housing 22, and moves reciprocally with respect to the housing.
