Low-dimensional　nanomaterials　are　receiving　widespread　attention　as　one　ideal　material　for　manufacturing　high-performance　electronic　switches,　which　play　an　important　role　in　improving　the　reliability,　working　speed　and　miniaturization　of　electron　devices.　This　article　reviews　16　classes　of　low-dimensional　nanomaterials　used　to　prepare　or　refine　micro-/nanoelectromechanical　switches,　molecular　electrical　switches,　resistive　switches　for　memory,　molecular　switches,　spin　switches　and　radio　frequency　switches.　By　classifying　the　size　difference　into　zero-dimensional　(0D)　nanomaterials,　one-dimensional　(1D)　nanomaterials　and　two-dimensional　(2D)　nanomaterials,　the　effect　of　nanomaterials　on　the　switching　performance　and　the　progress　of　application　in　related　electronic　devices　are　reviewed.　By　comparison,　we　discovered　the　advantages　of　low-dimensional　nanomaterial-based　electronic　switches　compared　to　conventional　semiconductor　switches.　Finally,　the　development　direction,　challenges　and　opportunities　of　low-dimensional　nanomaterials　for　improving　electronic　device　performance　are　presented,　and　future　research　directions　are　predicted.
