HES 4591-02-00-628 Exit Paddle Switch
The HES 4591-02-00-628 is a paddle-actuated exit switch engineered for access control systems and emergency egress applications in commercial and institutional facilities. This is not a sensor or monitoring device — it's a manual interface that allows authorized personnel and occupants to request or confirm exit through integrated access control logic. The 4591-02-00-628 delivers tactile, intuitive activation in high-traffic environments where reliability under repeated use is non-negotiable.
Key Features
- Paddle mechanism: Wide, easy-to-actuate paddle design reduces accidental activation compared to button-only alternatives and accommodates users with limited hand strength or mobility devices — critical in ADA-compliant installations.
- High-traffic durability: Rated for demanding commercial and institutional use, so the switch maintains consistent mechanical response over thousands of cycles without mechanical fatigue or contact degradation.
- Standard form factor: Integrates seamlessly with common exit control system architectures and mounting templates, minimizing custom fabrication and reducing integration labor.
- Indoor-rated construction: Suitable for climate-controlled interior installations where temperature and humidity remain stable; not recommended for exposed outdoor or wet environments.
- Access control compatibility: Works with standard access control wiring and panel inputs, allowing integration into existing door controllers and electrified lock systems without proprietary adapters.
- Manual actuation: Requires direct human contact to operate, delivering both a positive physical confirmation for the user and a discrete electrical signal to the control system — useful in scenarios where automatic or sensor-based activation is not desired.
Integration & Compatibility
The HES 4591-02-00-628 integrates with standard access control panels and electrified exit hardware via conventional wiring. It operates as a dry-contact input, meaning the paddle closure triggers a momentary signal that the access control system interprets as an exit request or confirmation. No special power supply, network connectivity, or software drivers are required — it pairs directly with door controllers, electric strikes, and credential readers that expect a standard pushbutton or request-to-exit (RTE) input. This simplicity makes the 4591-02-00-628 a suitable choice for retrofit installations where replacing existing infrastructure is not feasible.
Deployment Context
The 4591-02-00-628 is most effective in commercial buildings, hospitals, offices, and institutional facilities where exit traffic is steady and manual confirmation of egress is required by code or operational policy. It handles environments where occupants are familiar with access control workflows and can operate a paddle switch reliably. Avoid deployment in high-humidity, wet, or corrosive environments — those applications require higher IP-rated switches or stainless-steel variants from the same manufacturer family.
Frequently Asked Questions
Q: Does the HES 4591-02-00-628 require power?
A: No. The 4591-02-00-628 is a passive switch. It generates a dry-contact signal when the paddle is pressed; the access control panel provides any required power for downstream logic (lock control, relay activation, etc.).
Q: Is the 4591-02-00-628 suitable for outdoor installation?
A: No. The 4591-02-00-628 is rated for indoor use only. Outdoor or wet environments require a switch with a higher IP rating or weatherproof enclosure.
Q: What is the mechanical cycle rating of the 4591-02-00-628?
A: The switch is engineered for high-traffic commercial use and rated for thousands of actuations. Exact cycle specifications should be verified against the manufacturer datasheet or specification sheet for your specific deployment planning.
Q: Can the 4591-02-00-628 be used as a request-to-exit (RTE) device?
A: Yes. The paddle switch can be wired as an RTE input to electrified lock systems and access control panels, allowing it to serve as an occupant-initiated exit confirmation or door-release button.
Q: Is the 4591-02-00-628 ADA compliant?
A: The paddle design supports accessible operation for users with reduced hand strength or dexterity. Confirm full compliance with current ADA standards and local building codes for your specific jurisdiction and mounting height.

The HES 4591-02-00-628 paddle switch is a straightforward mechanical component — no firmware, no IP address, no analytics. That simplicity is exactly what makes it reliable for high-traffic exit applications. The paddle mechanism itself is the key differentiator: it distributes actuation force over a larger surface area than a push button, which means less force is required and accidental activations are less likely. In a 500-person office building with two or three main exits, that durability payoff over a three-to-five-year lifecycle is measurable in maintenance calls avoided.
Technical Highlights:
- Passive dry-contact design: No power supply or panel bus required. The 4591-02-00-628 simply bridges a contact when pressed. This eliminates a failure mode — if the switch fails, it fails open (no signal), not stuck-on, which is the safer failure state for exit applications.
- Paddle actuator versus button: Wider surface area and mechanical leverage mean lower actuation force. In ADA and accessibility audits, this reduces red flags and simplifies compliance documentation.
- High-cycle durability rating: Designed for thousands of activations in commercial high-traffic corridors. Mechanical contacts remain stable across temperature swings found in typical HVAC environments (65–75°F), so signal integrity remains consistent.
Deployment Considerations:
- The 4591-02-00-628 is indoor-only. Do not mount it in stairwells with exterior doors, loading docks, or any environment where moisture or temperature swings exceed typical office climate control. If you need an outdoor or wet-rated exit switch, step up to an IP67-rated variant or stainless-steel enclosure.
- Wiring is straightforward, but verify that your access control panel expects a dry-contact RTE input. Some older panels use polarity-sensitive inputs or require a pullup resistor. Confirm pinout compatibility before installation to avoid troubleshooting delays on a critical egress path.
The 4591-02-00-628 is the right choice for corporate office buildings, institutional facilities, and commercial spaces where exit traffic is regular and environmental conditions are stable. It is not a sensor — it's a user-actuated control point. Deploying it alongside proper door controller logic and electric strike wiring ensures that exit requests are both user-friendly and compliant with fire and life-safety codes.
