Securitron -u.s. MKA2 Mortise Key Switch Dpdt Single Gang

Product Description

The SECURITRON -U.S. MKA2 is a mortise-style key switch configured for alternate-action operation with a double-pole double-throw (DPDT) contact arrangement in a single-gang form factor. This switch is used to control access or egress functions within door hardware and exit device systems. It provides a secure, key-operated means to toggle a circuit state, making it a reliable component in electronic access control installations. Licensed locksmiths, security system integrators, and low-voltage technicians are the primary trades that install and commission this device.

The MKA2 is suited for commercial door hardware applications where a key-operated DPDT switch is required to control an exit device, electric strike, electromagnetic lock, or related access control hardware. Its single-gang mortise format allows it to be mounted in standard mortise cutouts commonly found in commercial door frames and jambs. It is appropriate for both new construction and retrofit access control projects requiring a tamper-resistant, key-actuated switching point.

Key Features

• Alternate-action operation holds circuit state between key turns without requiring the key to remain inserted
• DPDT contact configuration supports control of two independent circuits simultaneously
• Single-gang mortise form factor fits standard commercial door hardware cutouts
• Key-operated actuation provides a secure, tamper-resistant switching method
• Sold as a single unit, suitable for individual door or access point installations

Compatibility

Designed as an OEM-style replacement or upgrade component for commercial exit device and access control systems requiring a single-gang mortise key switch with DPDT alternate-action switching.

Installation Notes

Installation is typically performed by a licensed locksmith or access control technician familiar with commercial door hardware and low-voltage wiring practices. De-energize all connected access control circuits and verify zero voltage at the switch leads before beginning installation or wiring. Follow NEC guidelines for low-voltage control wiring and ensure the mortise pocket dimensions are correct before mounting to avoid damage to the switch body. Do not force the cylinder or cam mechanism during installation.
