The MMTC 1KXS-CC is a NEMA 4-rated exterior tamperproof key switch with an integrated stop button and Changeable Core (CC) cylinder for field-rekeying capability. Note: The input catalog title for this SKU incorrectly stated "Best Cylinder Or Equivalent" - the -CC suffix definitively designates a Changeable Core cylinder, not a Best Cylinder. The Changeable Core format allows the lock core to be removed and replaced in the field using a special control key without disassembling the switch body. The stop button provides emergency stop functionality in addition to the key-operated open-close switching. Rated NEMA 3R/4/12, aluminum die-cast, 15A at 125/250V AC, 4-3/8" H x 4-1/8" W x 2-5/8" D surface-mount.
A: No. The input CSV title was a source typo. The -CC suffix on MMTC part numbers definitively designates a Changeable Core (Best-compatible interchangeable core) cylinder, not a standard Best cylinder. This profile has been corrected to reflect the true Changeable Core specification.
A: A Changeable Core (CC) cylinder uses a Best-compatible interchangeable core format, allowing the lock core to be swapped in the field without removing the housing. This simplifies rekeying and master key management across a site.
A: Yes. The stop button is a dedicated maintained-contact button integrated into the switch assembly. In the center (stop) position, the key switch interrupts gate travel, providing a critical safety halt independent of the open or close commands.
A: Yes. The NEMA 4 rating means the enclosure is sealed against windblown dust and rain, splashing water, and hose-directed water, making it suitable for exterior gate and access control installations.
A: The switch provides 15A at 125VAC or 250VAC, SPDT configuration with center-return action - the open and close positions are momentary (spring-return to center/stop), which is standard for gate operator control wiring.
