Product Description
The MMTC CP-2B is a NEMA 3R/4/12 rated exterior ceiling pull switch that combines the rotating head mechanism (B suffix) with DPST (double pole, single throw) contacts, differentiating it from both the fixed-head CP-2 and the SPST CP-1B. The rotating head allows cord exit orientation to be adjusted post-installation, providing mounting flexibility for ceiling applications. Rated at 15A across 125VAC and 230VAC, the CP-2B simultaneously switches two independent circuits per pull actuation, making it suitable for dual-circuit gate control, 230VAC two-wire interruption, or paired safety relay applications. The aluminum die-cast enclosure shares the standard CP-2 housing profile (4"H x 3-3/4"W x 2-3/4"D).

Frequently Asked Questions
Q: What does DPST mean on the CP-2B, and how does it differ from SPST?
A: The CP-2B features DPST (Double Pole, Single Throw) contacts, meaning it simultaneously switches two separate circuits with a single pull actuation. This makes it ideal for applications requiring simultaneous control of two independent circuits, such as switching both line and neutral conductors for full isolation. Do not confuse it with the CP-1B, which is SPST and switches only a single circuit.
Q: What does the 'B' suffix in CP-2B signify?
A: The 'B' suffix in CP-2B designates a rotating head design. The rotating head allows the installer to reorient the pull cord exit direction without repositioning the entire enclosure body, providing significantly greater mounting flexibility for ceiling and overhead installations where cord direction matters.
Q: Is the CP-2B suitable for outdoor or wet-location use?
A: The CP-2B is rated for NEMA 3R/4/12, making it suitable for exterior and wet-location installations. NEMA 4 provides protection against windblown dust and rain, splashing water, and hose-directed water, while NEMA 12 adds protection against dripping and light splashing of non-corrosive liquids and dust. It is well suited for outdoor ceiling-mounted applications.
Q: What are the electrical ratings of the CP-2B?
A: The CP-2B is rated at 15 amps at 125VAC or 230VAC. Ensure your circuit load does not exceed 15A at these voltages. Because the DPST contacts switch two poles simultaneously, it is well suited for 230VAC two-wire applications where both conductors must be interrupted, or for dual 125VAC circuit control.
Q: How does the CP-2B compare to the standard CP-2 model?
A: The CP-2B and CP-2 share the same DPST contact configuration and general electrical ratings. The key distinction is the 'B' suffix: the CP-2B has a rotating head that allows cord direction adjustment after mounting, whereas the standard CP-2 has a fixed head. If installation geometry requires flexible cord routing, the CP-2B is the preferred choice.
