HES MCK-5-2 SGSS Stainless Steel Access Control Switch Plate
The HES MCK-5-2 is a plate-mount access control switching assembly engineered to interface electric locking hardware with door control logic and credential readers. Built from SGSS (stainless steel), this component delivers corrosion-resistant switching in both indoor and outdoor installations where durability and consistent mechanical performance over thousands of actuation cycles are non-negotiable. If you are deploying high-traffic secure entry points, emergency egress systems, or outdoor perimeter access, the MCK-5-2 serves as a foundational building block in your access control infrastructure.
Key Features
- SPDT switching mechanism: Single Pole Double Throw configuration enables two-position control—critical for signaling access-granted and access-denied states to your control logic without ambiguity. This alternative-action design ensures your door control system receives reliable contact transitions every time.
- SGSS stainless steel construction: Superior corrosion resistance compared to standard steel or plated finishes. Matters in coastal environments, humid warehouse facilities, or outdoor loading docks where salt spray and moisture degrade standard hardware within months. You avoid premature replacement cycles and associated labor costs.
- Momentary and latching operation support: Flexible configuration allows the MCK-5-2 to work in both momentary-contact scenarios (push button held briefly to trigger egress) and latching operation (contact maintained until reset). Adapt the switch to your existing door control logic without redesign.
- Compact plate-mount form factor: Designed to integrate seamlessly into door frame assemblies, strike plate installations, and request-to-exit (RTE) push-button housings. No retrofit brackets or fabrication—mounts directly into standard cutouts.
- Green factory-applied finish: Visual identifier for system integration and installation verification. Simplifies setup and auditing across multi-door deployments where consistency reduces technician errors.
- Repeated mechanical actuation durability: Engineered to withstand thousands of switch cycles without contact chatter, bounce, or mechanical failure—essential in high-traffic areas, emergency stairwells, and 24/7 facility access points where the switch experiences continuous use.
Integration & Compatibility
The MCK-5-2 functions as an interface point between electric strike assemblies, magnetic locks, credential readers (card readers, keypads, biometric scanners), and your access control panel or controller. The SPDT contact configuration integrates with standard access control wiring—no special signaling protocols required. Deploy the MCK-5-2 in request-to-exit push-button assemblies, door control cabinets, or as part of larger access control hardware ecosystems. When planning multi-door installations, reference your access control planning guide to ensure proper voltage and current ratings for your specific locking hardware.
Typical Applications
- Electric strike and electromagnetic lock integration—the switch signals when the lock should release.
- Request-to-exit (RTE) push-button assemblies for emergency egress compliance.
- Access control entry point interfaces where door open/closed state must be reported reliably.
- Emergency egress door systems in commercial and industrial facilities.
- Physical security infrastructure where outdoor or high-humidity environments demand corrosion-resistant components.
Deployment Considerations
The MCK-5-2 is a hardware component, not an intelligent controller. It provides no power, no logic, and no programmable functions—it is a passive switching interface. Your access control system (panel, controller, or reader interface) provides the intelligence and command signals. Ensure your control panel outputs are rated for the voltage and current draw of your electric locking hardware; the MCK-5-2 simply passes the signal. In outdoor installations, verify that your mounting enclosure and surrounding hardware also meet environmental requirements—stainless steel alone does not guarantee IP67 or IK10 ratings for the entire assembly.
Frequently Asked Questions
Q: Is the MCK-5-2 (often searched as MCK 5 2) suitable for outdoor installations?
A: Yes. The SGSS stainless steel construction resists corrosion in outdoor and coastal environments. However, the switch itself does not carry an IP rating—verify that your mounting enclosure and overall assembly meet your outdoor environmental requirements (IP66, IP67, etc.).
Q: What voltage and current can the MCK-5-2 switch handle?
A: Contact ratings depend on the specific configuration. Consult the MCK-5-2 datasheet or your control system integrator to confirm compatibility with your electric strike, magnetic lock, or auxiliary device power requirements.
Q: Does the MCK-5-2 require power to operate?
A: No. The MCK-5-2 is a passive mechanical switch with no internal power consumption. Power is supplied and controlled by your access control panel or reader interface.
Q: Can the MCK-5-2 be integrated into an existing access control system?
A: Yes, provided your control panel has wired outputs compatible with SPDT switching logic. The MCK-5-2 is a hardware interface and works with any standard access control system that supports relay or switching outputs.
Q: What is the expected service life of the MCK-5-2?
A: The stainless steel construction and mechanical design support thousands of actuation cycles. Actual lifespan depends on usage frequency and environmental conditions. High-traffic facilities can expect multi-year service life.
Q: Is the MCK-5-2 suitable for emergency egress applications?
A: Yes. The SPDT mechanism is purpose-built for request-to-exit (RTE) push-button assemblies and emergency egress door systems, ensuring reliable signal transmission for life-safety applications.

The MCK-5-2 is a workhorse component in physical security deployments where electrical switching reliability directly impacts door control and life-safety compliance. Its SPDT switching mechanism is the interface point between your access control decision (grant or deny) and the hardware that enforces it—a strike solenoid, magnetic lock, or auxiliary circuit. Stainless steel construction matters because standard plated steel fails within 6–12 months in humid or coastal environments, forcing costly field replacements. The MCK-5-2 eliminates that cycle.
Technical Highlights:
- SPDT alternative-action switching: Two-position contact ensures unambiguous state reporting to your control logic. No double-throw confusion or contact ambiguity—the panel sees a clean open or closed signal every time, reducing false triggers and egress delays.
- SGSS corrosion resistance: Stainless steel resists salt spray and moisture far longer than zinc-plated or painted finishes. In coastal facilities or outdoor loading docks, this translates to 3–5 years of maintenance-free operation versus 6–12 months for standard hardware.
- Momentary and latching capability: Single switch works in both push-to-exit (momentary) and sustained-hold (latching) configurations, eliminating the need to stock two different component types across a multi-building deployment.
Deployment Considerations:
- The MCK-5-2 is passive—it has no intelligence, no power draw, and no programmable logic. Your access control panel or controller provides all decision-making. Verify that panel outputs are rated for the voltage and current of your specific locking device before installation.
- In outdoor installations, stainless steel protects the switch mechanism, but your mounting enclosure must also meet IP66 or IP67 requirements. Do not assume the MCK-5-2 alone delivers weatherproof performance without proper cabinet and connector selection.
- The green factory finish is intentional—it signals a production-spec component. If you see corrosion, discoloration, or finish loss before installation, stop and contact the distributor. Damage in transit indicates possible internal corrosion risk.
The MCK-5-2 is the right choice for standardized access control infrastructure where durability and electrical reliability are priorities—warehouse loading docks, emergency stairwell egress, and multi-tenant commercial buildings where you need a single, proven component across dozens of door points. Pair it with proper environmental enclosures and correctly-rated control outputs, and you have a foundation that lasts.
