Title: Tactile feedback switch actuator
Inventor: SACH GARY M
IPC: H01H13/703
Filed: 1992-04-23
Granted: 1996-08-06
Abstract: A tactile  feedback switch actuator  (12)  for an associated force-actuated switch (52) has a key cap (22) linked to a collapsible dome (34) by an optical fiber (36), all of which are light-transmittable.  The actuator (12) is operated by manually applying an actuating force to the key cap (22) which exceeds the modulus of collapse of the dome (34).  In response, the dome (34) reversibly collapses  in  a  tactile  snapping  action  against  the underlying light-transmittable switch panel (54) having pressure-sensitive contacts (62a, 62b) embedded therein to change the operative state of the switch (52).  When the actuating force is withdrawn, the collapsible dome (34) elastically returns to its uncollapsed condition, while the switch  (52)  remains  in  its newly-actuated operative state.  The actuator (12) and associated switch (52)  are structurally integrated and aligned so that light-emitting   pixels    (60)    in   an   underlying electroluminescent panel provide visual feedback of the operative state of the switch (52).
