The MMTC 1KX-CC is a NEMA 4-rated exterior tamperproof key switch with a Changeable Core (CC) cylinder, providing a field-removable lock core that can be extracted and replaced using a special control key without disturbing the mounted switch body. This rekeying capability simplifies key management for commercial and industrial sites, allowing on-site core swaps and master-key changes without a locksmith visit. The 1KX-CC is built on the 1KX aluminum die-cast tamperproof platform rated NEMA 3R/4/12 for exterior and wet-location use, with SPDT momentary center-return contacts, 15A at 125/250V AC, and 4-3/8" H x 4-1/8" W x 2-5/8" D surface-mount dimensions.
A: The Changeable Core (CC) cylinder uses a special control key that allows the lock core to be removed and replaced directly in the field without removing the switch body from the wall or panel. This makes rekeying and master key changes fast, simple, and tool-free on the lock body itself.
A: No. Unlike the MMTC 1KX-IC which accepts Best SFIC (Small Format Interchangeable Core) cylinders, the 1KX-CC uses a generic Changeable Core format. The two core systems are not interchangeable and require different control keys and cylinders.
A: The 1KX-CC is rated NEMA 3R, NEMA 4, and NEMA 12, making it suitable for outdoor and wet-location installations. The aluminum die-cast tamperproof enclosure resists rain, splashing water, dust, and vandalism.
A: The switch is rated 15 amps at 125/250V AC with an SPDT contact configuration and momentary center-return action, supporting both Open and Close command outputs from a single key switch.
A: The 1KX-CC is surface mounted directly to a wall, post, or enclosure. No special sub-panel or recessed box is required; standard surface-mount hardware is used with the die-cast housing.
