Additional Information

A selector switch is a panel-mounted switch that switches between multiple discrete positions by means of a rotating operating handle. Each position corresponds to a preset combination of contact connections, used for selecting an operating mode or circuit path. Common indexing angles are 45°, 60°, or 90°, with contact actions being either maintained or spring-return types. Multi-layer cascade structures allow for an increased number of poles and positions to meet complex switching requirements. It is widely used in industrial control panels for manual/auto/stop mode selection, instrument range switching, and similar applications.
