Dual detent dome switch assembly |
摘要 |
An electrical switch assembly has a resilient dual detent dome carrying concentric electrically conducting pellets which sequentially contact conductive ends of traces on a printed circuit board in response to partial and full depression of the dome. The dome is designed to provide a first tactile feel when the first pellet contacts the circuit board and then a snap action tactile feel when the second pellet engages the circuit board.
