LiftMaster 02110 Indoor Key Switch with STOP Button
The LiftMaster 02110 is a keyed commercial control station for facilities that need authorized OPEN/CLOSE control plus a dedicated STOP button at the same indoor station. It is built for commercial and industrial operator control circuits, not residential wall-button wiring.
This model uses standard cylinder, a steel back box, and an architectural aluminum faceplate. The key switch is spring-return to center OFF, with the key removable only in that center position. The separate STOP button gives the user a direct stop command when the operator control circuit is wired correctly.
The 02110 family is often the better choice than the no-stop 02109 family when the station is expected to provide complete control of the door from one location. Cylinder type, NEMA rating, flush-mount box requirements, and operator terminal wiring should all be confirmed before ordering.

Technician Note
The 02110 family includes the STOP button that is missing from the 02109 family. Still, the stop terminals and control wiring must be verified so the button actually interrupts the operator command circuit as intended.
Before Ordering Checklist
- Confirm the station needs a STOP button at the same location.
- Verify the cylinder style is standard key cylinder.
- Confirm indoor NEMA 1 flush-mount installation is correct.
- Match OPEN, CLOSE, STOP, and common terminals to the operator wiring diagram.
- Do not substitute a no-stop 02109-style station where STOP control is required.
Professional Advisory
Keyed control stations should be installed and tested by a commercial door technician, especially where multiple control stations, timer-to-close, monitored entrapment protection, or constant-pressure controls are used.
