Product Description
The MMTC 1KFSX-CC is a NEMA 4-rated exterior tamperproof key switch combining a Changeable Core (CC) interchangeable cylinder with three-position Open-Stop-Close control for outdoor gate and access installations requiring field-rekeyable cylinders. The CC cylinder can be rekeyed or swapped without removing the switch from the wall - turning it with a control key releases the core for immediate exchange, reducing locksmith call-outs after lost keys or tenant changes. Open and Close positions are momentary with spring return to center Stop, ensuring the gate halts safely when the key is released. The weatherproof die-cast enclosure meets NEMA 4 specifications, sealing against rain, windblown dust, and splashing water for permanent exterior installations.

Frequently Asked Questions
Q: What does the 'CC' (Changeable Core) designation mean on the 1KFSX-CC?
A: The 1KFSX-CC features a Changeable Core (CC) interchangeable cylinder, which allows the lock core to be rekeyed or swapped in the field without removing the switch from its flush-mount enclosure. This is ideal for large facilities or property managers who need to rekey after tenant changes or lost keys.
Q: How does the 3-position Open-Stop-Close operation work on the 1KFSX-CC?
A: The 1KFSX-CC operates in three positions: Turn to Open (momentary), release to center Stop, and turn to Close (momentary). The spring center return automatically returns the key to the Stop position after each momentary activation, providing positive control over gate or door commands.
Q: Is the MMTC 1KFSX-CC suitable for outdoor use?
A: The 1KFSX-CC is NEMA 4 rated, meaning it is weatherproof and suitable for outdoor exterior installation. It is sealed against rain, splashing water, and windblown dust, making it appropriate for gate entry stations, parking facilities, and other exposed outdoor locations.
Q: What voltage does the MMTC 1KFSX-CC operate at?
A: The 1KFSX-CC uses dry contacts, meaning it does not have an internal power supply or specified operating voltage. It is compatible with virtually any gate operator or access control system that accepts dry-contact momentary inputs, typically systems operating at 12VDC, 24VDC, or 24VAC control circuits.
Q: How is the MMTC 1KFSX-CC installed, and is a surface-mount version available?
A: The 1KFSX-CC is a flush-mount model, designed to be recessed into a wall, pillar, or post. Installation requires cutting an opening to accept the back box (H=3-3/4" x W=3-3/4") with the faceplate (H=6" x W=4-3/4") overlapping the finished surface. A surface-mount version is available in the 1KXSX-CC series if flush mounting is not feasible.
