{"product_id":"liftmaster-k41-0081-000","title":"LiftMaster K41-0081-000 Interlock Reset Switch — Heavy-Duty Gate Operators","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K41-0081-000 is the interlock reset-switch service reference identified in documented heavy-duty gate-operator assemblies. HDSL24UL manufacturer parts information lists it separately from the reset-with-ID-resistor assembly, main board and gearbox disconnect. Match the installed switch, wiring and mechanical actuation before ordering. The interlock has a specific role within the operator; it is not a generic accessory switch or permission to bypass an open interlock so a gate can continue running with an enclosure or disconnect problem.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeavy-duty assemblies listing K41-0081-000\u003c\/td\u003e\n\u003ctd\u003eCheck the complete model and installed switch.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHDSL24UL repair information\u003c\/td\u003e\n\u003ctd\u003eIdentifies this exact interlock reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReset-with-ID-resistor assembly\u003c\/td\u003e\n\u003ctd\u003eSeparate service item and function.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGeneric limit or accessory switches\u003c\/td\u003e\n\u003ctd\u003eNo automatic substitution established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFaulty disconnect or enclosure actuation\u003c\/td\u003e\n\u003ctd\u003eMust be diagnosed rather than bypassed.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Interlock Mechanism and the Circuit\u003c\/h2\u003e\u003cp\u003eAn interlock switch works with the mechanism that actuates it. A fault may result from a bent bracket, worn linkage, loose mounting or damaged wiring rather than the switch alone. Have qualified personnel inspect those elements together and compare the installed arrangement with the correct service diagram. Do not change the actuator position simply to conceal incomplete engagement or another mechanical defect.\u003c\/p\u003e\u003cp\u003eRecord the original terminal identification and circuit function before removal. The SPDT designation describes the contact arrangement, while the operator diagram determines how those contacts are used. Keep that distinction clear when comparing replacements. After service, test the intended interlock response in every required operating state; ordinary door movement by itself does not demonstrate that the interlock is functioning.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eK41-0081-000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct\u003c\/td\u003e\n\u003ctd\u003eInterlock reset switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented example\u003c\/td\u003e\n\u003ctd\u003eHDSL24UL heavy-duty gate operator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDifferent assembly\u003c\/td\u003e\n\u003ctd\u003eReset with ID resistor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate component\u003c\/td\u003e\n\u003ctd\u003eGearbox disconnect\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical and terminal requirements\u003c\/td\u003e\n\u003ctd\u003eMatch exact switch and operator diagram\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecord the full HD operator and installed switch details.\u003c\/li\u003e\n\u003cli\u003eConfirm K41-0081-000 versus reset-with-ID components.\u003c\/li\u003e\n\u003cli\u003eInspect switch actuation, connections and associated mechanism.\u003c\/li\u003e\n\u003cli\u003ePlan correct interlock and complete gate safety tests.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the K41-0081-000 interlock reset-switch service item.
