摘要： The present disclosure relates to tactile switch assemblies having stepped printed circuit boards for use with snap-domes in surgical instruments. In accordance with one aspect of the present disclosure a tactile switch assembly for use with a surgical instrument includes a substrate, an inner terminal disposed on an upper surface of the substrate and having a first height, an outer terminal disposed on the upper surface of the substrate and substantially surrounding the inner terminal and having a second height which is greater than the height of the inner terminal and a snap-dome secured to the substrate and having a periphery engaged to and in electrical communication with the outer terminal. The snap-dome is depressible through a range wherein, upon inversion of the snap-dome, an apex of the snap dome electrically connect the inner and outer terminals.
