Alarm Controls KA-107A Momentary Key Switch 2 Keys

Product Description

The Alarm Controls Corporation KA-107A is a momentary key switch designed for access control and security applications. Momentary operation means the switch is active only while the key is held in position, then returns to its default state upon release. The KA-107A ships with two keys that are keyed alike, allowing both keys to operate the same cylinder. This type of switch is commonly installed by electricians and low-voltage security technicians in commercial and light industrial settings where operator-controlled momentary switching is required.

The KA-107A suits installations where a keyed momentary input is needed to trigger door release systems, gate operators, elevator controls, or other access control equipment. Its keyed-alike configuration simplifies key management on sites where multiple authorized personnel need access to the same switch. The unit quantity is one switch per package.
