MMTC CP-2 NEMA 4 Exterior Ceiling Pull Switch DPST
The MMTC CP-2 is the DPST version of MMTCs exterior NEMA 4 ceiling pull switch. It is used where a pull-cord station must switch two poles at the same time or where the control wiring requires a DPST contact arrangement rather than the simpler SPST configuration. Typical applications include commercial overhead doors, rolling doors, industrial access points, gates, dock controls, and parking equipment where a ceiling pull provides convenient manual activation. Correct replacement is important because DPST and SPST pull switches can look similar from the outside but serve different wiring needs. Before ordering, match the contact configuration, enclosure rating, mounting location, and operator wiring diagram. This model is a control device only and must not be substituted for a safety sensor.
Common Applications
- Automated driveway gate and commercial gate control stations
- Commercial overhead, rolling steel, and sectional door operator inputs
- Loading dock, warehouse, parking, and service-bay manual activation points
- Access-control interfaces where a keyed or pull-cord dry-contact command is required
- Exterior or damp-location installations when the enclosure rating matches the job
Compatible With
Select door operators, gate operators, industrial controllers, dock controls, and access systems that require a compatible DPST pull-station input. Use where the wiring diagram calls for a double-pole single-throw pull switch. Confirm if the original installation needs CP-2, CP-2B, CP-2SW, or another MMTC ceiling pull variant. Compatible with commercial door operators, rolling steel door operators, sectional overhead door operators, automated gate operators, barrier gate controllers, loading dock controls, parking controls, and access-control panels when the control board accepts the same low-voltage dry-contact command and the enclosure style is suitable for the location. Verify the original wiring diagram, contact type, stop circuit requirements, mounting style, and enclosure rating before ordering.

Technician Note
Control stations can look alike but behave differently electrically. Match the original contact action and wiring diagram before replacing a key switch or pull switch. A switch with the wrong contact type can cause no operation, unexpected operation, or a missing stop/control function.
Before Ordering Checklist
- Confirm the MMTC part number on the existing switch or job specification.
- Match SPST, DPST, open-close, center-return, heater, and mounting requirements before ordering.
- Verify the operator control board accepts the same dry-contact input and does not require a different station.
- Check enclosure rating, weather exposure, conduit entry, and mounting clearance.
- Do not remove or bypass photo eyes, safety edges, loop detectors, or other required safety devices.
Professional Advisory
Have a qualified gate or commercial door technician handle wiring when the circuit is not clearly identified, when heater power is involved, or when the operator has unsafe movement, missing safety devices, or line-voltage control wiring. This product is for manual command input only and should never be used to bypass monitored entrapment protection.
Product Questions and Answers
What is the difference between CP-1 and CP-2?
CP-1 is SPST while CP-2 is DPST. The correct choice depends on the number of poles required by the operator wiring.
Can CP-2 be used on a low-voltage control circuit?
It can be used where the control circuit accepts the correct dry-contact switching, but the circuit rating and wiring diagram must be verified.
Does CP-2 include a rotating head?
No. CP-2 is the standard DPST ceiling pull switch. CP-2B and CP-2SW are related rotating-head or angled-pull versions.
Is CP-2 suitable outdoors?
It is built as a NEMA 4 exterior pull switch, but the installation still needs proper mounting, sealing, and wiring practices.
Can CP-2 replace a safety edge or photo eye?
No. CP-2 is an activation control and does not provide monitored entrapment protection.
