MMTC 1BXT Nema 4 Exterior One Button Surface Mount Control Station Double Pole
The MMTC 1BXT is a compact exterior one-button control station with double-pole contacts in a non-metallic weather-resistant enclosure. The T suffix is commonly used on MMTC control stations to indicate the double-pole contact version, which gives the installer more contact flexibility than a basic single-contact push button. A 1BXT may be used for a single open, close, stop, cycle, reset, alarm, or auxiliary command depending on the operator terminal being controlled. It is often chosen where the control circuit needs both contact states, isolated circuits, or a compact outdoor push button with a smaller footprint than the metal 1BX enclosure. This product should be matched by contact style and enclosure requirements, not only by the number of buttons.
Compatible With
This control station is compatible by control-circuit design, not by brand name alone. Use it only when the operator or control panel supports the same button functions and contact style.
- Select gate operators and commercial door operators with single dry-contact command inputs
- Control circuits requiring a compact exterior one-button station with double-pole contacts
- Parking, barrier gate, access-control relay, and equipment-control applications using a single push-button input
- Exterior surface-mount locations where a non-metallic NEMA 3R/4/12 style enclosure is preferred
- Replacement for existing 1BXT stations where the double-pole contact arrangement is required

Technician Note
The T suffix should not be read as tamperproof. For this family it indicates double-pole contact construction; compare against the original wiring diagram before replacing a standard 1BX. These stations are typically wired to low-voltage or control-voltage terminals, but the actual circuit rating and wiring method must follow the operator manufacturer instructions.
Before Ordering Checklist
- Confirm the exact MMTC part number on the old station or parts list.
- Confirm the number of buttons and the intended button functions.
- Check whether the application is interior or exterior and whether the enclosure rating is appropriate.
- Match the contact style, including momentary, maintained, single-pole, double-pole, normally open, and normally closed requirements.
- Compare the enclosure footprint, conduit entry, and available mounting space.
- For any stop or emergency-stop circuit, verify the control logic before changing parts.
Professional Advisory
Do not use a push-button station to bypass monitored safety devices, entrapment protection, interlocks, or required stop circuits. If the operator moves unexpectedly, has damaged controls, or involves high-voltage wiring, have the system checked by a qualified gate or commercial door technician.
Questions and Answers
What is the MMTC 1BXT used for?
The MMTC 1BXT is used as a manual control-station device for compatible gate, commercial door, overhead door, parking, or equipment-control circuits. The exact button function depends on how the control station is wired to the operator or panel.
Is the MMTC 1BXT compatible with all gate and garage door operators?
No. It may be used with select operators that accept the same dry-contact input style, button count, enclosure type, and contact arrangement. Always match the wiring diagram and the original control-station function before ordering.
Can this control station be used as a safety device?
No. This is a manual command device. It is not a monitored photo eye, safety edge, loop detector, or entrapment protection device, and it should not be used to bypass required safety devices.
What should be checked before replacing an existing 1BXT?
Check the original part number, button labels, enclosure footprint, conduit entry, contact type, stop-circuit logic where applicable, and whether the operator expects normally open or normally closed control contacts.
Can a similar MMTC station with the same number of buttons be substituted?
Not automatically. Similar-looking MMTC stations may differ by enclosure material, NEMA rating, double-pole contact construction, latching versus momentary action, stop contact logic, or mounting footprint.
