The LiftMaster 02108 3-Button Indoor Flush Mount Control Station is a wired push-button station used to command a compatible LiftMaster commercial or industrial door operator from a fixed location. This style of station is different from a residential wall console: it is a simple dry-contact control device that connects to the operator control terminals and sends the operator the OPEN/CLOSE/STOP command signals allowed by the selected wiring type. In real installations, these stations are commonly mounted near sectional overhead doors, rolling steel doors, dock doors, warehouse doors, maintenance doors, and controlled commercial entrances where staff need direct local control.
The main fitment questions are button count, mounting style, enclosure rating, and control wiring type. A 3-button open/close/stop station should only be used where the operator manual supports that function. Indoor NEMA 1 stations are for protected interior areas, while NEMA 4/12 outdoor stations are better suited for exposed or wash-down-prone commercial locations. If the station does not include a STOP button, a separate stop control may be required on many industrial operators. Always match the old station and operator wiring diagram before replacing a control station.
Commonly used with LiftMaster industrial operators where a flush-mounted 3-button station is specified:
| Manufacturer | LiftMaster |
| Product Type | 3-button OPEN/CLOSE/STOP commercial control station |
| Part Number | 02108 / 02-108 / MMTC-PBC-3 |
| Mounting Style | Indoor flush mount |
| Enclosure / Rating | NEMA 1 flush-mount station with stainless steel faceplate and standard 2 x 4 electrical box style |
| Application | Hardwired commercial door operator control |
| Button Function | OPEN normally open, CLOSE normally open, STOP normally closed; verify MMTC-PBC-3 contact layout |
| Contact Type | Dry-contact push-button station, verify NO/NC contact arrangement by wiring diagram |
| Compatible Operator Type | Select LiftMaster commercial and industrial door operators with matching control wiring |
| Safety Notes | Not an entrapment protection device; do not bypass stop or safety circuits |
Commercial door controls directly affect door movement. Do not modify wiring to bypass stop functions, constant-pressure requirements, monitored safety devices, interlocks, or code-required controls. Use a qualified technician when replacing controls on powered commercial doors.
It is used as a hardwired 3-button open/close/stop control station for compatible LiftMaster commercial or industrial door operators where the control circuit supports that button layout.
It is intended for commercial and industrial door operator control circuits, not typical residential smart wall controls or Security+ wall consoles.
No. It is a command station only. Required photo eyes, sensing edges, monitored entrapment protection, and operator safety circuits must remain in place.
Match the old station part number, enclosure style, button count, and the operator wiring diagram. The wiring type matters more than the door brand alone.
Low-voltage control wiring should still be installed according to the operator manual. If line voltage, door movement, or safety circuits are involved, use a qualified commercial door technician.
