LW5D16/D1044.4 is a 16A 500V 3 Position 4Pole rotary selector transfer changeover cam switch with 16 screw terminals. This device is designed to provide reliable multi circuit switching in electrical control panels and equipment, enabling coordinated control of several circuits from a single control point. Key benefits Simultaneous four circuit switching: the 4pole design allows control of four separate circuits with a single rotary action, simplifying wiring and improving coordination. Transfer and changeover capability: supports switching between circuits or sources, enabling safe and efficient changeover in control applications. Secure wiring with 16 screw terminals: provides reliable, vibrationresistant connections and neat wire management for panel installations. Robust rotary cam mechanism: built for repeatable operation and long service life in industrial environments. Compact, panelmount design: suitable for integration into standard electrical control panels and equipment. Key attributes Model and type: LW5D16/D1044.4, Rotary Selector Transfer Changeover Cam Switch Electrical rating: 16A current, 500V maximum voltage Configuration: 3 positions, 4 poles Terminals: 16 screw terminals for connections Application: intended for use in electrical control panels, machinery, and equipment requiring a 3position, 4pole changeover switch Construction: rotary selector mechanism designed for reliable panel mounting and operation Applications and use cases Use case 1: Control panel source transfer. Switch between two power sources or operating modes for critical equipment, enabling quick and safe changeover without external wiring changes. Use case 2: Multicircuit control in a single operation. Simultaneously switch four separate loads (for example, four drives or loads in a machine) in one action to simplify control logic and ensure coordinated operation. Use case 3: Mode selection for testing or maintenance setups. Route power or signals to different circuits in a lab, test bench, or production line to support configurable experiments or maintenance tasks.
