Product Features
Technical Overview
The MKN2 features a 5 Amp plunger switch rated for reliable performance in access control circuits. It supports dual-voltage LED operation at 12 or 24VDC, with the bi-color LED providing clear status feedback. The SC keyway allows integration with common key systems, maintaining key control consistency.
A backing bracket enables straightforward mounting with any 1-1/4" [32mm] or 1-1/8" [28mm] mortise cylinder, though the cylinder itself is not included. An additional switch position on the bracket permits activating another switch by turning the key in the opposite direction, adding flexibility for multi-function setups.

- 12/24VDC compatible
- Bi-color for status feedback
Secure Mounting
Anti-tamper screws prevent unauthorized removal, while the backing bracket ensures stable integration with standard mortise cylinders.
- Anti-tamper screws included
- Bracket for 1-1/4" or 1-1/8" cylinders
Multi-Function Capability
An additional switch position allows activating a second switch with the opposite key turn, enabling complex control scenarios without extra hardware.
- Additional switch position
- Opposite-direction activation
Deployment / Use Cases
The Securitron MKN2 Mortise Key Switch is ideal for applications requiring key-operated electrical control in security systems. It serves as a manual override or activation point in access control setups, integrating seamlessly with electric locks and alarm panels.
Common deployments include commercial building entry systems, where the switch controls electric mortise locks; alarm panel arming/disarming stations, providing a physical key option; and secure room access points, enabling key-based circuit activation. Its compatibility with standard mortise cylinders simplifies retrofits and new installations alike.
Electric Lock Control
Integrate with electric mortise locks to provide key-operated locking and unlocking, adding a manual control layer to automated access systems.
Alarm Panel Integration
Use as a key switch for arming or disarming alarm panels, offering a secure physical alternative to code or remote controls.
Physical Profile
The MKN2 has a compact length of 1.13" (28.58 mm) with a 26D finish, ensuring a low-profile installation that fits within standard mortise cylinder assemblies. The backing bracket accommodates both 1-1/4" [32mm] and 1-1/8" [28mm] cylinder sizes, though the cylinder is sold separately. This design minimizes footprint while providing secure mounting with anti-tamper screws.
Physical fit matters beyond raw measurements because it affects placement, airflow, cable routing, handling, and day-to-day service access. Buyers often review this section to reduce installation surprises and confirm whether the product will sit cleanly in the intended desk, shelf, rack, cabinet, or shared workspace.

FAQ
What is the electrical rating of the Securitron MKN2 switch?
The MKN2 features a 5 Amp rated plunger switch, suitable for controlling typical loads in access control and alarm circuits. This rating ensures reliable performance when switching electrical power to connected devices like electric locks or alarm panels.
What voltage does the LED on the MKN2 require?
The bi-color LED operates on either 12VDC or 24VDC, providing flexibility for integration with different power supplies commonly used in security systems. The dual-voltage design allows installation in varied electrical environments without requiring additional components.
Which mortise cylinders are compatible with the MKN2?
The backing bracket permits integration with any standard 1-1/4" [32mm] or 1-1/8" [28mm] mortise cylinder. Note that the cylinder itself is not included with the switch, so you must source it separately based on your specific lock or panel requirements.
What security features does the MKN2 include?
The MKN2 includes anti-tamper screws to prevent unauthorized removal after installation. Additionally, the SC keyway provides controlled key access, and the compact design with 26D finish offers a discreet, secure appearance in access control setups.
Can the MKN2 activate multiple switches?
Yes, an additional switch position on the backing bracket allows another switch to be activated by turning the key in the opposite direction. This enables control of two separate circuits or functions from a single key operation, adding flexibility for complex security configurations.
What applications is the MKN2 designed for?
The MKN2 is designed for use with mortise cylinders, electric locks, and alarm panels. Typical applications include commercial building access control, secure room entry systems, and alarm panel arming stations where key-operated electrical switching is required for security or override functions.
