This panelmounted rotary cam selector switch offers a reliable ONOFFON function with a latching action, designed to fit SZW26, LW2620, LW28, and LW39B variants. It uses a 48x48 mm panel cutout and provides 9 selectable phases with 36 terminal screws for wiring flexibility and neat connections. Key benefits Maintains chosen position: latching mechanism locks the switch in place after each rotation, reducing the risk of accidental changes in operation. Flexible circuit routing: 9 phases allow selection among multiple circuits or configurations from a single switch, enabling compact control of complex panels. Robust panel integration: 48x48 mm panel size suits standard control enclosures and provides a clean, professional look in industrial equipment. Easy wiring and access: 36 screws offer ample terminals for organized wiring, easier maintenance, and clear fault tracing. Compatibility across model families: designed to match the SZW26, LW2620, LW28, and LW39B families for reliable replacement or upgrade in existing panels. Key attributes Functionality: rotary cam selector switch with latching ONOFFON action. Phases: supports 9 selectable phases. Terminals: 36 screws for wiring connections. Panel size: 48 x 48 mm mounting area for standard 48x48 mm panels. Mounting: panelmounted installation for secure, flush fit. Compatibility: intended for use with SZW26, LW2620, LW28, LW39B model families. Applications Industrial machinery control panels: quickly switch between multiple motor winding configurations or circuit paths while preserving a chosen setting. Electrical test benches: route signals to different test circuits without losing the selected test channel. Automation and process control: implement compact multibranch control where several circuits must be selectable from a single, robust switch. Usage considerations Ensure proper panel cutout and mounting hardware for a secure fit. Verify electrical ratings and wiring scheme align with your specific application requirements. Follow standard electrical safety practices during installation and maintenance. In summary, this latching ONOFFON rotary cam selector switch provides a durable, spaceefficient solution for multicircuit control, with broad compatibility across common 48x48 mm panel installations and essential wiring flexibility through 36 terminal screws.
