Product Description
The MMTC 1KXL-CC is a NEMA 4-rated exterior maintained-contact key switch with two latching positions - On and Off - fitted with a Changeable Core (CC) cylinder for field-rekeying capability. As a maintained switch, the 1KXL-CC holds its On or Off position after key release, providing sustained access control state without operator presence. The Changeable Core format allows the lock core to be removed and replaced in the field using a control key without disassembling the switch, simplifying rekeying and master-key program changes in commercial environments. Built on the 1KXL aluminum die-cast platform: NEMA 3R/4/12 rating, 20A at 125V AC or 15A at 250V AC, 4-3/8" H x 4-1/8" W x 2-5/8" D surface-mount.
Key Features
- MAINTAINED (latching) 2-position ON/OFF operation - switch holds its selected position after key release; not momentary
- Changeable Core (CC) cylinder enables full field rekeying without removing the switch from the enclosure - ideal for facilities requiring periodic key changes
- Compatible with interchangeable core master key systems for integrated facility-wide key management
- NEMA 3R / NEMA 4 / NEMA 12 rated aluminum die-cast enclosure for weatherproof exterior use
- Surface mount design for straightforward installation on walls, posts, or gate operator enclosures
- Contact rating: 20A @ 125V AC or 15A @ 250V AC for reliable switching of gate operators and control circuits
- Binary ON/OFF operation - no center/neutral position; switch is always in either the ON or OFF state
- Reduces response cost for lost-key incidents - core swap replaces an expensive service call
Compatibility Guide
- Gate operators requiring sustained ON/OFF access control
- Garage door operators with key switch inputs
- Commercial gate systems requiring periodic rekeying
- Facilities with master key or interchangeable core key systems
- Industrial equipment requiring keyed power control
- Any 20A @ 125V AC or 15A @ 250V AC switching application where field rekeying is anticipated

Frequently Asked Questions
Q: Is this a momentary or maintained switch?
A: No. The 1KXL-CC is a MAINTAINED (latching) switch. Turning the key to ON locks the switch in the ON state, which it holds even after the key is removed. Turning the key to OFF holds the switch in the OFF state. The switch only changes state when actively operated with a key - it does not spring back like a momentary switch.
Q: What does Changeable Core mean and what is the advantage?
A: A Changeable Core (CC) cylinder uses an interchangeable core format that can be removed and replaced in the field using a special control key - no disassembly of the enclosure or switch required. This makes the 1KXL-CC ideal for facilities that need to rekey periodically, respond to lost keys, or integrate into an existing interchangeable core master key system.
Q: Can the 1KXL-CC be rekeyed without removing it from the wall?
A: Yes. This is the primary advantage of the 1KXL-CC over the 1KXL-BC. The interchangeable core can be swapped in the field using a control key, allowing you to rekey the switch without tools, electricians, or removing the unit from the wall. This significantly reduces the cost and downtime associated with key security incidents.
Q: Is the 1KXL-CC suitable for outdoor installation?
A: The enclosure is rated NEMA 3R, NEMA 4, and NEMA 12, making it fully suitable for outdoor surface mounting exposed to rain, sleet, and windblown dust. The aluminum die-cast housing provides durable protection in exterior gate and access control environments.
Q: What is the contact current and voltage rating?
A: The contacts are rated 20A at 125V AC or 15A at 250V AC, making it compatible with most gate operator control inputs, lighting relay circuits, and light industrial switching applications.
Q: When should I choose the 1KXL-CC over the 1KXL-BC?
A: The 1KXL-CC is best suited for facilities, schools, multi-tenant properties, or any site where keys are distributed broadly and periodic rekeying is expected. If key control is static and rekeying is never anticipated, the 1KXL-BC with its Best Cylinder may be the more cost-effective choice.
