Liftmaster K76-33672, 1 BUTTON CONTROL STATION
The LiftMaster K76-33672 is a one-button control station style service part used on select HCT overhead gate operator systems. It is also commonly referenced as APBS1 and appears in some catalog listings as a reset switch. On HCT operators, this type of push-button station is used for operator control or reset functions depending on the wiring and system configuration.
Because the same part may be described differently by suppliers, it is important to compare the existing control station, label, wire function, and parts diagram. This is a commercial gate operator service part and should not be substituted with a standard residential garage wall button.
