SZW26/LW2620 7 Phases ON OFF ON 20A 660V 28 Screws 102 Knob Changeover Cam Rotary Switch Panel 64X64mm Why this switch helps Simple, reliable manual switching for multicircuit or multiphase needs. The SZW26/LW2620 provides clear ON–OFF–ON control in a compact panelmounted package so you can isolate, changeover, or select circuits without complex wiring changes. rated switching capacity reduces the need for additional contactors or relays when switching loads within the rated limits (20A, 660V). A 102 knob changeover arrangement gives two selectable ON positions with a center OFF for safe, unambiguous control. Key features and attributes Model: SZW26/LW2620 Configuration: 102 changeover cam rotary switch (ON – OFF – ON) Phases: 7 Phases — suitable for switching seven separate circuits or poles Rated current: 20A Rated voltage: 660V Termination: 28 screws for secure, conventional screwterminal wiring Operation: Manual knob changeover with clear positional selection Mounting: Panel mount, 64 x 64 mm panel size Functionality and performance Camtype rotary action provides positive mechanical switching between positions for repeatable electrical contact. Rated for up to 20A and 660V — designed to handle moderate power circuits within these limits. 28 screw terminals allow straightforward wiring of multiple circuits, reducing installation time and improving serviceability. The 102 configuration enables changeover capability (two selectable ON positions) with a center OFF position for safe interruption. Typical applications Industrial control panels: Use as a selector or changeover switch for machine control, process selection, or isolation of subsystems. Power distribution and motor control: Switch between supply sources, control multiple motor windings or circuits, or select operational modes with a single knob. Equipment and test benches: Convenient manual selection of lines or circuits for testing or maintenance where clear ON/OFF/ON control is required. Installation and compatibility notes Designed for panel mounting with a 64 x 64 mm panel cutout or compatible front panel. Connect using the 28 screw terminals; ensure wiring and torque follow local electrical codes and component manufacturer recommendations. Use within the rated limits (20A, 660V); do not exceed these ratings for longterm reliable operation. Why choose this model Combines multicircuit switching capability (7 phases) with a compact panel footprint. Straightforward 102 knob changeover layout for clear operator control. Multiple screw terminals simplify wiring for complex switch requirements. Practical tips Verify panel cutout dimensions (64 x 64 mm) before installation for a correct fit. Label knob positions or wiring where multiple circuits are involved to avoid operator confusion. Confirm load characteristics and switching duty to ensure operation within 20A/660V ratings.
