Key specifications Model: LW8D10D4043B Type: Changeover rotary switch Positions: 3 Poles: 3 Terminals: 12 screws Current rating: 10A Package: 1 piece Suitable applications Electrical control panels requiring manual selection among three circuit paths. Instrumentation and automation cabinets that route signals or power to different subsystems. Prototyping and test benches where three independent circuits must be switched between three positions. Use cases Power or signal routing in a small machine: use the three poles to independently switch three circuits through three selectable positions. Mode selection in a benchtop automation setup: assign each pole to a different operating mode and switch among them with a single knob. Multicircuit testing: route a common input to three different test channels by selecting the desired position for each circuit.
