{"product_id":"liftmaster-k23-2016","title":"LiftMaster K23-2016 Open \/ Close Limit Switch — Documented Operator Controls","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K23-2016 is the open\/close limit-switch service reference offered for documented operator travel-control arrangements. Manufacturer SL595 parts information identifies this switch separately from its limit nuts, reset switch and complete limit-box assembly. Select it by the exact operator and electrical diagram, not simply by the presence of a mechanical lever. The switch helps the control recognize a travel endpoint when correctly installed and adjusted; it does not replace entrapment protection or correct an operator that overruns because of a different mechanical or wiring fault.\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\u003eRepair lists specifying K23-2016\u003c\/td\u003e\n\u003ctd\u003eMatch the installed switch and control diagram.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented SL595 arrangements\u003c\/td\u003e\n\u003ctd\u003eIdentify the correct limit position and generation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK23-2017 or other switch references\u003c\/td\u003e\n\u003ctd\u003eNo automatic interchangeability from similar numbering.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComplete limit-box repairs\u003c\/td\u003e\n\u003ctd\u003eDifferent assembly scope from one switch.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSafety edges and photo eyes\u003c\/td\u003e\n\u003ctd\u003eSeparate protection functions; not replaced by a travel-limit switch.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eMatch Both Contact Arrangement and Mechanical Actuation\u003c\/h2\u003e\u003cp\u003eAn inconsistent stopping position can originate in the electrical switch, its wiring or the mechanism that actuates it.

A loose holder or damaged adjustment component can prevent a sound switch from being operated at the correct point.\u003c\/p\u003e\u003cp\u003eRecord the original terminal connections and identify how the limit mechanism actuates the switch. Use the exact circuit diagram and manufacturer mounting arrangement. A similar case shape does not establish the correct contact transfer or operating position. After replacement, verify the prescribed travel endpoints and associated controls under the model-specific test procedure. Electrical continuity at one position is not sufficient to demonstrate correct operation of the complete limit system.\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\u003eK23-2016 \/ 23-2016\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComponent\u003c\/td\u003e\n\u003ctd\u003eOpen \/ close limit switch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented example\u003c\/td\u003e\n\u003ctd\u003eSL595 limit-control arrangement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate items\u003c\/td\u003e\n\u003ctd\u003eLimit nuts, reset switch and limit box\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectrical rating and terminals\u003c\/td\u003e\n\u003ctd\u003eMatch current switch and exact 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 operator model and installed switch markings.\u003c\/li\u003e\n\u003cli\u003eMatch K23-2016 and its exact terminal arrangement.\u003c\/li\u003e\n\u003cli\u003eInspect limit actuation, wiring and mechanical travel.\u003c\/li\u003e\n\u003cli\u003ePlan model-specific adjustment and safety tests after repair.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the individual K23-2016 limit switch.
