MMTC LCE-3 NEMA 1 Three Button Interior Single-Gang Control Station Product Details
The MMTC LCE-3 is a compact three-button interior control station for operators that need local OPEN, CLOSE, and STOP commands from a traditional single-gang style wall location. It is often used where space is limited or where the control station needs to fit a cleaner interior wall layout. Unlike larger three-button flush stations, the LCE-3 uses a more traditional single-gang format. It should be selected by wiring function, not just by button count, because the related LCE-3A has a different terminal arrangement for CLOSE and STOP. This control station is intended for protected NEMA 1 interior locations and should not be used in exposed weather, washdown areas, or hazardous-location applications.
Compatible With
May be used with commercial overhead door operators, rolling steel door operators, industrial door controls, dock door controls, select gate operators, barrier arm operators, and access control systems that accept low-voltage dry-contact push-button commands that accept compatible OPEN, CLOSE, and STOP dry-contact control wiring from an interior single-gang station. Commonly associated with commercial overhead door operators, rolling doors, dock doors, service doors, industrial operators, and protected gate control stations. Related models include LCE-3A, PBC-3, 3BF, PBS-3, 3BFL, and exterior 3BX/3BFX families, but these differ by terminal layout, enclosure rating, and mounting format.

Technician Note
The LCE-3 is compact, but compact does not mean universal. Verify whether the existing station uses the standard LCE-3 terminal layout or the LCE-3A double-pole CLOSE/STOP configuration.
Before Ordering Checklist
- Confirm the station is LCE-3, not LCE-3A.
- Verify single-gang wall box fit.
- Check OPEN, CLOSE, and STOP terminal requirements.
- Confirm the location is interior/protected.
- Review the operator manual before changing stop-circuit wiring.
Professional Advisory
A stop circuit should never be bypassed to make a wall station work. If the operator requires normally-closed stop wiring, wire the station exactly as specified by the manufacturer.
