LiftMaster 02110 /02-110 Two-Position Key-Control Switch — With Stop Button

The LiftMaster 02110 supplier SKU identifies the 02-110 two-position key-control switch listed in manufacturer commercial-operator literature with a stop button. The catalog describes an indoor flush-mount arrangement with an architectural faceplate and notes other mounting options as separate configurations. Confirm the exact supplied version before ordering. This is a wired control station, not a wireless credential reader or a guarantee of outdoor suitability. The switch functions and wiring must match the operator’s supported control scheme.

Compatibility — Models, Versions and Exclusions

Choose the Station Configuration and Control Function

Record the operator model and determine what the two key positions must command under its wiring instructions. A key switch is selected by both its physical configuration and its contact behavior. Have the installer compare the exact supplied station with the operator diagram before ordering. A familiar faceplate or key shape does not establish that the contacts match the intended control inputs.

Plan a location that preserves required visibility, access and separation from moving equipment. Inspect any existing box and wiring for suitability and damage. An indoor flush station should not be exposed outdoors based on the availability of a different weather-rated version in the same family. After installation, verify the key commands, stop function and the door’s complete required protection response under controlled conditions.
