Important Notes

• Verify part number 578261701 before ordering
• Confirm compatibility with your specific Husqvarna equipment model, engine, wiring harness, and ignition-system configuration
• The exact switch dimensions, mounting diameter, number of terminals, terminal arrangement, connector style, electrical rating, switch positions, key configuration, circuit functions, and compatible equipment models are not identified in the supplied product information
• The supplied information does not identify whether this switch uses a removable key, integrated key, rotary control, push/pull mechanism, or another operating configuration
• Do not assume the switch provides specific OFF, ON, RUN, START, accessory, choke, or lighting positions unless confirmed by the applicable equipment documentation
• Compare the original switch's part number, overall shape, mounting interface, connector configuration, terminal arrangement, operating positions, and wiring connections
• Ignition switches that appear physically similar may have different internal circuits, terminal functions, connector arrangements, or electrical ratings
• Do not substitute an ignition switch based solely on appearance or the number of visible terminals
• Inspect associated wiring harnesses, connectors, terminals, grounds, fuses, relays, starter solenoids, batteries, starter motors, ignition modules, and safety switches for wear, corrosion, looseness, or damage
• Starting or ignition problems may be caused by components other than the ignition switch, including a weak battery, damaged wiring, poor ground, blown fuse, faulty relay or solenoid, starter problem, ignition-system fault, or activated safety interlock
• Diagnose the applicable electrical circuit before replacing the switch when the cause of the problem is uncertain
• Never bypass or permanently defeat operator-presence switches, neutral switches, brake switches, blade or PTO interlocks, or other equipment safety circuits
• Disconnect the battery or other electrical power source as appropriate before removing or installing the ignition switch
• Label or document electrical connections before removal when individual terminals or connectors could be incorrectly reinstalled
• Protect electrical terminals and connectors from moisture, corrosion, dirt, and physical damage
• Do not rewire, bridge terminals, modify connectors, or alter the ignition circuit to force compatibility with an incorrect switch
• This listing is for the ignition switch; do not assume that ignition keys, wiring harnesses, connectors, mounting nuts, bezels, relays, fuses, solenoids, or other electrical components are included unless specifically stated
• After installation, verify proper switch fitment, mounting security, electrical connections, ignition operation, starting function, shutdown function, and all applicable safety-interlock functions before returning the equipment to normal service
